am i being victimised at work?

So here it goes this may be a long read but i need answers as its wearing me down!
i am 25 years old and a mother of 2 beautiful children i have never worked in my life as ive never needed to as my hubby brings in enough, both my kids are now in school and i was getting bored and going insane looking at the same walls every time so i thought i would try my luck at getting a little part time job around the corner at my local pub/restaurant i have been here just over 7 months now and this weekend just gone i flipped! i was like a ticking time bomb waiting to go off!
basically im surrounded by 16 year olds so there all children compared to me and of course i come to work to pay my bills not for pocket money i have noticed in the last 2 months when ever i am on shift i seem to do all the work and i mean all the work im either constantly taking out the food or making puddings! on saturday night i was put on puddings again which at this point i have had enough of it being me all the time, we was super busy and at one point i had 22 tickets on and there was a 45min wait on puds as there was so many bearing in mine you do them on your own theres just the one of you, first thing to happen was i went out to to a table to take the puds and when i came back to my work station every single one of my tickets had been tampered with who ever it was has cut out the table number so i had no idea where these puddings where going! i looked like a headless chicken wondering around the restaurant tying to find the right customers! then the second occurrence was when i came back again! someone had squirted all the custard over my work station the toffee sauce was everywhere my drink (last one i had) had been poured all over the floor, digestive biscuits where all crushed up and sprinkled everywhere and also a apple pie was put in the microwave and had exploded to guessing someone putting it on a high time! i have physically had enough i feel so drained and miserable being there i cant take no more it makes me feel sick having to go to this place as the manager is horrible its like treading on egg shells every time your in i come to work to do my job not to mess about i have 2 children like a said i haven't got time to be childish and immature i just cannot believe it happened to me and then last night (Sunday) i wasn't in the best of moods as i had been crying all day from Saturdays antics i had a banging head ache and surprise surprise i was on food! i just wanted to clear tables and have a rest i was on it from 5-8 without going to the toilet or even having a drink and it was boiling!! no one helped me i was so busy there was so much food and starters to take out! and of course its never that simple when you also have to get the customers sauces then to top it of i started feeling angry and hot and quite frankly peed of! the deputy told me to take 5mins outside which i didn't and with that i just started crying and shouting and one of the young girls that works that started having ago at me and shouted i have asked if you wanted any help, but she didn't i asked numerous times from people and they either didn't hear me or just ignored me i don't know what i am doing wrong i always keep myself to myself and never have i had any issues with anybody i was outside cooling down for half hour and talking to the duty manager and she was talking nonsense to me i just don't know what to do i feel like crap when i come home im never happy and i don't want it to make me ill i have kids to think about i just don't know?
this isn't the first time things have happened to me (meaning the Saturday night occurrence)
a few months back i bought a new river island coat for 60 pound i didn't have it long and someone hacked at the sleeves with a pair of scissors! and we never did find out who it was! and also i had a couple of cigarettes go missing out my pocket , i just don't know what to say or do i feel useless and that nobody take me seriously or listens i feel like im being bullied! can anyone help or relate?
i absolutely hate my job ive never hated anything somuch in my life!!

I think you need to move on if you can. There are lots of issues that from where I sit cannot be resolved just with your input, and I doubt you will get that from management.

Maybe have some time off and look for something else. Maybe reskill for something that has better job satisfaction.

Good luck.

Personally I was against you at the beginning with your obvious pretentious nature towards those younger than you, but after further consideration of the events that followed, I've managed to form what I believe to be an unbiased opinion.

So to start, You chose to get a part time job to relieve the insanity that comes with boredom. But after a clear abuse towards you of your coworkers, you're now imbued with an anger/disadvantaged form of the same emotion that inevitably drove you to acquire a job in the first place.

I think you just have to decide among 4 choices (more possible choices given the strength of your ingenuity and creativity, but these are what I've come to.)

1. quit your job and return to the previous boredom
2. quit your job and search for a more suitable work environment. maybe something in an office setting with people a little closer to your age group to keep you more comfortable.
3. Realize that you are only one person, and can only do so much. Continue at your current job with your capabilities in mind. and any "shortcomings" anyone sees, are purely their opinion. As long as you are working your best, that is all that matters. (Make peace with the situation)
4. Raise a little hell, set some people straight. after that, figure out if it's worth it to continue on or leave the job.

As you've probably noticed that 2.5 of my responses inform the possibility of leaving your job. That is because, I think that your current job is doing you more harm than good, and isn't worth whatever they are paying you. I personally think that you should move on to something better. Do with that whatever you will. Hopefully this was somewhat helpful without being overly-critical. I apologize if this wasn't helpful to you.
