Symptoms of Depression. I in depression?

Hello, i am 27 year old. I always have a kind fear in me when i am outside my home. At night my body wants to sleep but i do not want to sleep. I always wanted to be awake more and more time. Though i am not utilizing my time properly but i do not want to sleep. Now i do not like to eat lunch at office. I am skipping my lunch on a gap of 1 or 2 day. Sometimes i wanted to cry alot but i don't. I do not want talk to people due to my stammering problem. My confidence is at its lowest point. I feel i do not love myself. I am stuck in my life. All responsibility of work and family looks like a huge burden to me. Sometimes i want to ran away from my this life and wanted to stay from all, in a hill or a far away area. From outside may be my life looks very normal but in my head i am not good. I am living without any aim in life. I never had any mentor or guru of any kind who can show me right way to go. I think i am completely lost now. Right now i feel like i want to cry. am i in depression?
