lasttimearound don't worry you wouldn't have been the first person to cry at yoga. At a time when I was absolutely fine I had a conversation with another 'fine' person about how certain positions, weirdly, made us feel really emotional/tearful for no discernible reason.
It's difficult with emotionally abusive, or even physically abusive parents to do the whole no contact thing. I always think to myself that 'at least it didn't go further than that!' and like you, 'at least they fed and clothed me'. Keep those boundaries up. I think it's hard though…I always feel my parents gave me an excellent upbringing compared to theirs…like each generation improved on the previous. That they did their best, given the circumstances. But it is important to hold onto the fact that it isn't, and wasn't ok, and that it needs to be dealt with.
I've had a good week until today. Lots of exercise, which is really good. No alcohol, which has helped. Then today- I'd asked one of my kids school for something really important twice this week, once by email, once in person, and they didn't do it. I needed it by today. It's hard for me to ask due to logistics (kids at different schools). So it's back to feeling like we just get in everyone's way, that we aren't welcome around here (we moved) and that everyone just wishes that we would disappear, although we don't have anywhere to disappear to. I don't mind it when I feel bad about myself, but I don't like it when I bring my kids into that negative thinking mode. They are good kids, and all of them have the opportunity to do well for themselves in the future, but I worry that I am going to make them fall into the same way of life as me. Depression, negativity, relationship failure, unemployment. That's probably catastrophising though isn't it?
