I have been trying to stop over thinking and analysing for a long time but the more i try the worse it becomes.Sometimes i feel so anxious that i get a headache .I have tried being friends with carefree people thinking some of their attitude would rub off onto me but nothing seems to help and i am starting to get jealous of some of my friends who seem to be so carefree and dont care about what others might say or think and just live their life in their own ways and keep doing their best.How can i be like them.I always used to be extremely self conscious since i was 14 .Though that has reduced a lot now and i feel much better ,i still worry a lot about people and my best friend sometimes gets annoyed with my anxiety and she suggested to me the 'so what technique?' and to think about the worst scanario and to ask that question to myself.A professor of mine also told me to do the same but that too doesnt really work always.Would i have to live like this all my life and how do i get myself to stop over analysing things and just enjoy life like my friends.
