Losing my faith

Hello everybody

To begin with, me writting this and confessing it are very painful and heavy on my heart.

Iam a 21 years old male, unfortunately i had oral sex with a female i dont know why i could not stop myself from doing it, i wish i could go back with time so i wont do it again.

The problem is i feel like i lost my soul, whats destroying me is deep inside i didnt have that much of regret, so not regretting it makes me angry from my self (if you know what i mean, this cycle. being mad for not regretting it), also, i guess this is because of the pornography i have been watching.

Iam very sad i might have lost my iman and soul, i have been struggling lately with my iman, i even used to pray all the 5 prayers daily but i dont know what happened i cant keep doing this regularly anymore. I feel iam on the edge of losing my faith, i know if i continue like this i will lose it.

I wish i had some one in real life were he/she can understands me and help me.

Help me what should i do ?

Please do not reply " stop watching porn" if it was that easy i would have done it

Lastly, is oral sex considered as zina?

please have Duaa for me

Thanks in advance

I hope this will help
