Feeling bad depressed Is it normal?

Hello friends I want to share with you because I have strange feelings these days I have already done almost 4 days without porn masturbation and orgasms . I am limited to any sexual content I am focused on work, fitness progress and goals in life but I feel sad lonely it's like i'm missing something i don't have much motivation it's hard for me to fall asleep. At times I start to want to sit and watch porn and masturbate my brain tries to lie to me but I do not give up. I still remember my ex-girlfriend and we write to each other from time to time, I am still in pain that we are separated and I have the feeling that we will together again and I still hope and that makes me keep thinking about her
and in principle it's quite complicated with us...


Is it normal to feel that way?
I'm not sure, but I think I've been feeling that way since I stopped PMO
