Writing my heart out - Newbie

I started watching porn when I was 15 or 16 now 20. At that time I was in school and it didn't affect my grades much since I was so good at studies. I used to be shy boy in school &talking to girls online or offline made me nervous.

Now I am at home studying for atough professional exam . there is lot of time available and sometimes I burnout too. Sometimes I watch porn & masturbate once or twice a day daily it takes up to an 1 or 2 hours many a time less. As far I know I am not addicted to it some times I take off days too.

But I realised porn can harm the way I look at girls or relationship . It is not helping me to overcome my shyness & confident around girls. Also I want to avoid being addicted it to it in future. It is not depicting any of features of realistic sex as far as I know. Italso make me insecure about my dick size rather than being happy with what I have.

Apart from this I have a weird habit of thinking about a imaginary girlfriend /wife or future crush and talking to her. Maybe it is bcoz I am lonely while studying for exam. People are there around me like family or some friends but all are busy or feel it difficult to open up

Presently the issue is that since I watch porn & masturbate I tend lose time & energy. I sleep more as well .I Don't know why cant focus or concentrate on studies from the time I started studying for professional exam. I have miserably failed once too. It feel like I forget something I study quickly & it demotivates me. I also feel lot of pressure & stress.

I want to change myself all over. Develop my personality & be confident about who I am. I love to interact with more girls & have more close friends who I can confide on.
Wake up everyday with fresh mind, study hard and pass the professional exam with flying colours. learn to love myself & take a stand for myself.

For this I need to stop watching porn & masturbate in order to dedicate time to my studies same time be focused.

From today I start my NoFap journey

It would be great to get some help for problems I face. Share your views about it
Nice to be here &writing my heart out.
