Hi Fuzzy, I'm thinking a lot of the mistakes you're mentioning are more the responsibility of others??? Maybe people who took advantage of you or manipulated you when you were vulnerable, because you lacked self esteem, because you'd been led to/wanted to believe..............so I'm not sure you need to take as much ownership (or any ownership in some cases!!!) of things that have happened or choices you made???
And you know even if it's hard to forget at times, even if people throw things at you........I reckon you can still "forgive" yourself, you can still accept/be compassionate towards yourself despite/regardless of what has happened, you can still put that blame in it's rightful place (and I'm sure that will be on others shoulders at times!!) and move on from it.............
And as for the ability to trust................maybe after the first step of really recognising that some people out there can be trusted (everyone might make mistakes at times and compromise trust, but there will be people you can still trust with the most important things or in certain areas), it can be about finding the right people to trust.........and then maybe little by little...............it might take a lot of time but...............
I think maybe working through some of the things people have done to you a bit more might help a little with that though???? With someone/people who really understand!!!
You already know what I think of what your T said!!
Just don't forget there can be really genuine, caring, understanding people out there (and on here!!), hey??
And that you so deserve to have people like that in your life!!
