I'm scared to talk with people, or even just being in their "aura" or something. I am so scared, I need some help, what can I do with this, or what is this, why can't I just talk to people? Every day, I'm crying and shaking, just because someone asked me a question or just said hi. I am scared of my teachers asking me a question. When they do this I'm crying inside. And I just can't trust anybody in real life, not even my parent or my best friend, who is supporting me mentally every day. I'm too scared to tell them my true feelings. My grandmother died in February, after that I've been diagnosed with depression, but I was scared of people before too. I can't even eat or sleep because of these things, my body is telling me that I need to eat, need to sleep, but I can't do that, I don't know why. I'm literally starving myself, and I always tell myself "yeah I'm okay, if I do that I will survive the day", but inside I feel awful and weak. I sleep 4-5 hours a day. I can't talk to a therapyst, I can't talk with people in real life and I'm scared to tell them. I feel like posting my problems on social media is the only way out. 

I am so sorry if my english is so bad, I'm a foreigner, and I probably mispelled  so much words.

Please help me, I don't know what to do, whats happening and why I'm so confused and scared.
