I've had a very turbulent and violent childhood that I escaped from at 16yo. It took awhile to trust people again and I eventually did in my early 20's. My new motto back then was trust everyone first until they prove you wrong. Unless of course there was legit red flags. It made my life easier and manageable. And then I made friends with a circle of folks that were less than admirable and positive. Bad mistake on my part. I was used, lied too, taken advantage of and pulled into infighting. It took awhile for it to go full blown toxic and I had to cut it off 10 years ago by moving. I'm 47yo now. Have a great partner but I still have trust issues even thi she hasn't done anything really to violate my trust. It's not easy for me to trust anyone anymore and I feel I'm way too guarded.

Is there any books or youtube vids or advice even that can help me heal and try to trust people again? I do go to therapy but I feel I need to change therapists. Any advice can help. Thank you.
