I am 19.I fear i can not focus.For the last 4 years every day i have taught oabout what if i didn't focus when a teacher ask me somthing,or when i speak with someone,or when i read,or etc,in almost any sitaution.My life would be over.I started feeling anxious when talking to people.I can not eat,i feel anxious,noxious prior to having an acitivity in front of other people.I distract my concentration whenever i want to focus.And i feel guilty,i feel deserve not concentrating,i feel it is my fault,i am to stuborn.THe thing is that there are an infinte things for wich i pottentially may feel guilty so i don't know what to do.I feel very insecure,i am not very sure it is my fault ,but i oscilate.it *****/This fear of not being able to concentrate started 4 years ago when i started masturbating,i was feeling very guilty for this,very bad and i still feel like this.Every time i do it makes me feel worthless,stupid,idiot.I told my parents a few month ago that i masturbate to get a relief but it didn't work.Now i feel guilty for not telling them my sexual fantasys and sexual thoughts.There are so many things i could tell them about my sexuality but i am ashamed,i feel i will explode if tell them,but there infinite.I still fear i might not focus and sometimes i distract my focus intentionally,i feel like i am being punished.
How should i find out what is really bugging me>?How should i find the root of my problem?
