I don't want anymore?

I'm just completely done with everything. My work is wearing me out, all the stress, my colleagues, the guests, everything, and I never get even five minutes of peace, not even on my break. At home, it's my parents who won't leave me alone and constantly annoy me. My whole family is crap, everyone is either disturbed or dependent on something, I have no one I can turn to or who cares about me, let alone any family relationships at all because my family is just completely broken and disturbed. I never get any peace, not at home, not at work, not on my days off, not on vacation, and I just can't and don't want to anymore. When I have time off, I'm so stressed just from the thought of having to go back to work, I never really have any free time or a chance to sleep in. For years I've struggled with anxiety disorders, which my parents have no idea about because they're too busy with themselves and don't believe I could have any problems, even though they're responsible for 90% of my mental health issues. I'm socially completely awkward and downright embarrassing. I'm constantly scared when I'm around people and can't hold a conversation at all. Of course I've never had a relationship in my entire life, not a first kiss, nothing, and yet I long so much for someone who loves me and is there for me. Someone with whom I can just be myself and cuddle and just be happy. I feel so alone, even when I'm out with friends, and I simply hate myself. I hate my body, I hate the way I look, but no matter how much I change myself, I'm always dissatisfied. I've also realized that whenever I feel really shitty, I either fall in love with someone unattainable, suddenly become obsessed with something, or cling to someone just to have something to distract me and make me happy for a while, until at some point it no longer works and I look for the next thing. I've lived like this my whole life and I just have no will or strength left. I just want it all to end. I wish I could swap places with someone, just get rid of my life. I don't want this anymore and I don't know what to do anymore…
