So I've turned to this forum because it's a place where I can remain anonymous, let it out, talk to someone - hopefully if anyone replies and trust that no one will use it against me

I've reached my breaking point with everything in life and I feel like no one cares or cares in the way I need them to............well I know that's not entirely true....but I feel like I can't talk to anyone or trust anyone

Anyways, I've been trying sooo soo hard to remain resilient and optimistic and handle my relationships better, it's just that I feel like I don't have support and that everyone is so ###$ fake. I'm struggling at work to put on a front, I get told of by a lot of people and hardly ever complimented for anything I do right.......I get put down by my TL indirectly for my performance by telling me to take leave on certain days because she only has room for 6 people to work (xmas dates) in front of my colleagues and I'm not even on contract to only work when there is work I'm full time employer. She also confronted me for being argumentative but I wasn't trying to be agrumentative to my colleagues, it's just that I was pressured and trying to find the answer - just felt like she was taking their side a little.......I try to be friendly and outgoing but because everyone is pressured and they have their clicks and I'm new I feel left out - doesn't help that I'm the only female on the phones (although my TL is a female) I come home feeling depressed after work......sometimes I feel like some of the guys are controlling, authoritative & insecure....like they can't and will never admit it when I'm right.......
it's effecting me .........the only thing that keeps me going at work right now is this one guy who I feel is a mentor to me (2nd team leader) - he's soo humble and knows how to handle me when I'm pressured/stressed but most of all he's very helpful.... God only knows how much I appreciate this - I'm trying not to play the victim here, but I honestly do feel bullied and I can't open up because people judge me and tell me to toughen up and to shake it off. I don't have any friends because I just moved and I'm putting on weight again (after I lost 30kgs - gained it all back) and I'm trying to get it together because I want to live life. I know that having friends will help with resilience to simple problems and I know this may be a simple problem but I feel sooo out of control and honestly been crying out of control....
I also have a brother and sister-in-law with kids......they're okay too but they have hurt me.....I don't know how to deal with this? .........it's because I need my family to fully accept and support and help me the way I am ..........I remember there was a fishing trip that my brother organized......and because I had gained weight (I think this is the reason) him & my sister-in-law hinted that they didn't want me to go with them - so it was just my dad and sis and brother who went.......
Please help me not feel like a victim.....I know I'm strong but I can't open up to confront people because I've learnt the hard way that people use it against you...
Anyone please reply, I honestly appreciate any advice or encouragement......just feeling so ###$ hurt, angry, tired and depressed......there's so much more I want to say and a lot more that is going on but i'll leave it at here for now........I hope I haven't broken any of the forum rules lol - didn't wanna read that $#%^ to be honest, just need to vent......i'll put a trigger warning at the top just incase haha.
Thanks for reading if you've reached this far and I hope your day is going better than mine........sometimes reaching out to strangers is a lot more helpful than reaching out to family.
