Unemployed, depressed and no idea what to do

Hi guys, I'm really struggling mentally at the moment due to unemployment and I am really struggling to do anything anymore or see a way out. I really don't know what to do.

Basically I've struggled with depression, anxiety, social anxiety and low self esteem for quite a long time now, mostly due to being horrifically bullied most of the way through school and having a narcissistic mother and sister. I recently finished uni with a masters degree and I've been unemployed for about 6 months now and its really affecting me badly. I am trying to get a job in marketing but I'm having no luck whatsoever, even with a marketing internship under my belt. I'm applying for all the entry level jobs that I am qualified to apply for, but I haven't had an interview since early February. On top of this, many of the jobs that do appear on job boards have a stupidly high skills requirement, which practically expects entry level job seekers to be marketing experts! Obviously I do not fall under this category, having only done an internship for a couple of months and its not possible to learn everything in that time. So I am cut out from a lot of jobs with no other option than to volunteer. I am going to start volunteering tomorrow, but I know that it will not give me amount of skills that employers are expecting. I feel utterly hopeless and its got to the point that I've stopped caring about marketing altogether. Just thinking about it makes me feel more depressed and I'm now constantly questioning whether its right for me despite being absolutely sure when I did my internship. Even doing a search on a job board triggers off bad depression and completely ruins the whole day for me. I feel like I am never ever going to get into marketing so what's the point of even trying. The lack of interviews obviously shows I'm not good enough. My confidence is absolutely rock bottom and I'm absolutely panicking about the volunteering tomorrow because I'm convinced I won't able to do the work very well and that I'm terrible at marketing, despite the fact my internship supervisor thought I had a talent for it. Its got to the point now where I feel there is no point to my life on a fairly daily basis and that if I can't get a decent job that I don't hate then my life is a waste of time. I just don't want to know anymore and I'd permanently bury myself into a fantasy world if I was able to. I feel I have absolutely no worth to the world. I do not have the will to take up any hobbies except the occasional video game because there's just no point to my existence. Does anyone know what to do or think? I feel like I'm in an impossible situation to get out of.

With regards to employers: remember that you are not the only person that doesn't have 30 years of professional experience at the age of 25 (which is what they indeed seem to expect). At the end, employers pick from the pool that exists. I would actually think that the jobs with the most unrealistic expectations are the ones to apply for because a whole lot of other job seekers will look at the ad, go "wha?" and move on to something more plausible.

Are you getting any help for your depression and self-esteem issues? Counselling of some sort? Is there job counselling available where you live?

Your life is much more than having a job. I should know, I've been on disability since 2011. Volunteering is a great idea because it will look good in your CV. I hope that goes really well. Remember the thing with volunteering is that you can walk out if you don't like it and look for something more suitable.

Big hugs. I hope you find a great job soon!
