tldr; confidence varys and internal game only works at times when it wants to. I want to make it work all the time.

I am having trouble with my inner game--not just for seduction but in my life overall. I am a 18 year old college student, and my confidence changes depending on my external surroundings. If I am not wearing nice clothes, my confidence WILL go down. If someone says something negative or rude, that brings down my whole day, etc. I over analyze way to much. I feel like i'm stuck and could really use some advice because i feel my internal game only works when it wants to.
