Healing and Social Anxiety

Most times I can get back on track to self-care and doing the things I need to do take care of my mental health. This morning I went to journal and one of the prompts was to name how I need support and a list of people I can count on for support. This gave me a lot of anxiety and honestly felt like it started to undo the process I had made this morning because I couldn't and can't think of a single person I can count on for support. This is difficult for me because relationships with others is the source of my depression and anxiety and it is easier for me to think of things I can do to help myself, but time after timer I keep coming to things and therapists saying that I need a support system. I don't have a support system and it is difficult for me to create support systems or have friendships or relationships with peope where I can trust them and they haven't broken that trust. I have such a difficult time figuring out whether I am being the difficult one and to give the person who hurt me another chance or if that person really just doesn't care about me and/or our relationship. Logically I can go back and see that I have communicated and done all I can to make the relationship better, but that type of honest effort isn't given back for whatever reason. It is hard to move forward and make progress in my anxiety and depression without a support system and I'm not sure how to see prompts or hear things about how important support systems are when I know I do not have one and don't see myself having or creating one anytime soon.
