Hey, if your trust issue huge to the point u can't trust people u are close to and humans generally, then I recommend to get a pet like dog,cat,turtle...etc but in that case, dog is the best. start to give trust to the animal as if it human being. Talk to it, become close to it and so on. How that will help you? It will help you feel the trust and what its like to give a trust to organism and living thing, this is from my firend personal experience, I am not sure how much of this will help you after all I am not an expert and, I apologize for any spelling mistakes.
many people have told me that, but to be honest I don't like having a pet in my house 🥺
Awww it's okay!!! Some people dislike that idea you are not the only one.
