I realized today I have almost no true friends
Why do you think you have no true friends?
I have a hard time trusting everyone
Trusting people is hard but you have to put the work in a relationship to make them work. Relationships only work when both people are putting in the work.
You've probably never been betrayed so it's easy for you to say that but for me it is not that easy.
I am sorry that you have been betrayed in the past but it is in the past and to have relationships in the future, you have to leave that in the past. By putting in hard work in your relationships now, they might succeed where others didn't.
