I guess the subject says a lot.
Without my full life story, I've always struggled to fit in, from school I was bullied to the point where I was homeschooled for a significant period. Relationships have always turned abusive, either physically, mentally or both. Work? Same pattern... To put it bluntly, I'm what you would describe as a "perennial victim".
A couple of years ago, I met the most amazing person I've ever met and now I'm really struggling because I don't know how to react to that, for the first time in my life, I've been happy but I can't help but take every single arguement to heart, every single comment I turn into a negative, I turn into the worst possible scenario and in turn, I make them miserable because I'm always on edge about everything and I started to become extremely needy. I have absolutely no idea how to act around someone that's nothing like anyone else I've ever had in my life, I have worked on this and I'm getting a bit better with it but I'm so scared I'll push them away before I fix this because I can't control my emotions, I have absolutely no idea how to fix things, every time I try and do something to fix things, I make it worse because I'm trying so hard, I've spoken to them about this but it's hard to communicate this and it's hard to put this across without it A) looking like an excuse for me acting like I do and B) looking like I'm some emotional trainwreck (I might be biased but I'm not one of these, I have so much love to give for them, I just don't know how to express it properly)
I feel like every single person that's ever screwed me over (and there is an extremely long list) is just continuing to achieve what they wanted to for all those years. I am alone at the moment and basically I have no one else to use as a sounding board, I guess I just needed to get that off my chest but if there's any advice, I'm all ears
