How do you build trust and have faith in people?? 

A friend of mine told me to jst “blindly” have trust and faith and I just can’t do that. 

I’ve been through 2 much trauma to jst put my trust into people like that /: 

So..... how do I build it? I tell ppl things. I open up to them. But I never trust that they WONT abandon me. And it causes me to split a lot.
