After my dad passing away I started to feel less confident and it led to me feeling miserable and weak most of time.. I do things which people tell me to do even though I don't want or agree with it..  I lie so that I can escape from any situation which can be solved if you're confident. 
I was not like this. I ask permission for so little and silly things that mum is getting annoyed. At this point I don't understand what I'm doing when I am around people.. I am looking for people's acceptances and opinions which I didn't in the past..
