Since past 2-3 years I observed a change in my behaviour like I feel alone even in crowed like classrooms or with friends group. I mostly chat with few people not even with my family. Mostly I prefer to be quite & same time also want people to understand me. Every night I search for videos like Spirit animal or peace of mind. Also I while talking with someone about my feeling I sound like stone cold. Many times In night mostly I feel to cry & get that little heart pain like feeling when we are about to cry. I also smoke but stopped it just cause a girl whom I like told me but even while chatting I get angry on her too. Is it any kind of depression?
