I don't trust my Family/Friends

Hi, 

I have social anxiety and because of that only 3, but 3 loyal friends. But we're all going through something difficult. The mother of one friend (Let's call him Bob) died. Another friend (Let's call him Steve) has depression and gets no support from his family. His family does the exact opposite. They tell him he shouldn't overreact. And my third friend (Let's call him Kyle) is propably about to expierience a loss too. Bob and Steve reach out to me. For Steve I'm the only one (Besides his therapist) who helps. Kyle is still thinking positive, but he may also reach out for me in the future. And me? I help them all and carry everything they're concerned with. But I don't trust my family or my friends with my problems. I'm overwhelmed and bottled up my stress for 6 moths now. In the past week I also had trouble focusing and sleeping. I also distance myself from my friends. Normally it takes me between 1-10 minutes to answer to a message. But in the past week I ignored them for more than a day. I also feel guilty because they need my help sometimes. I'm also easily annoyed by small noises for example. I feel like I'm going to explode when I hear chewing. I never talked about my feelings. I never had anyone listen, so I don't know how it feels. This is the first time I reach out, but I'm way too scared to reach out for a listener or even therapist. I don't trust them. I don't know what I'm expecting from this, but I just needed someone to finally hear me. Maybe that's a start. Thanks for reading, if you did. It means more than you probably realize.
