Is it PIED , FLAT LINE or medication withdrawal symptoms

My age is 25 years, I'm a virgin and I'll get married to a beautiful lovely girl after few months maybe 4 or 6 months from now (we are still arranging) and according to my culture it's not normal to have sex outside of marriage.

I'm diagnosed with OCD and borderline personality disorder.

I always relapse (with binge ) after 10 ,30 or even 60 days of nofap on hard mode( no masturbation and no porn)

In the last few months maybe from April or mars I was taking (flavouxmine) but during this time I was binge in relapse every 7 or 10 days and I noticed the following

Point 1:
When I was younger than now maybe when I was 22 or younger. I was having good erection and sometimes I was having very strong morning erection. Especially during my streaks.
And when I was much younger maybe when I was 11 or 12 I was having erection from anything. Even vibrating of bus may give me erection.

Point 2:
In the last period I noticed I'm having some how a weak erection during relapse and about 10 days ago I find myself wanting to watch porn and masturbate but in the same time I had no erection but I really want to do it and I relapsed and binged as usual although I was having so weak erection and mild weak erection for few seconds then go back to so weak erection. In addition in the last few relapses I noticed once I touch myself I find myself ejaculating quickly and not able to hold my ejaculation for longer time as I was but although all of these things I still ejaculate for maybe 5 or 6 times in one session and I feel I need more. I was just stoping because I feel my heart was really hurting me

Point 3:
After what happened in point 2 I decided I will stop my medication suddenly, because since I started this medication obsessions went away but I was relapsing in schedule. So I did
And currently suffering from some medication withdrawal symptoms and
I'm on the day 6 of stoping medication
And day 4 of no porn
And day 2 of no masturbation
And I won't masturbate or watch porn again ever because even the intensity of porn I watch increased I won't mention the categories I was watching in the last period from time to time. And I told my closest friend about my problem with addiction to porn because when I feel I want to relapse I'll tell him directly and he accepted to help me.
Currently,
I'm so anxious and even sometimes I cry for no reason even If I did every positive thing
Studying (different subjects)
Reading ( at least 10 pages )
Exercising (50 push up ,50 crunches, 50 leg raises ,30 squats) no gym available currently.
Sticking to my intermittent fasting plan.

For example today I only slept for 4 hours and I waked up feeling so anxious and nervous.

My questions are
1-Is it PIED that I was hearing about? Or it's flat line? Until the day before last relapse I was having erection during my sleep but it was also
So weak, but currently no erection at all, it's zero either wake up or sleep. And I feel I push myself on liking girls or trying to look at them in a sexy way just to get erection.
All I'm concerned about is having erection and good morning wood or wet dream and anything else is out of my mind
So is it a flat line , PIED or medication withdrawal symptoms?

2- the girl I'm with is so beautiful and lovely and even sometimes I feel I don't deserve her what should I do? And she loves me too but I'm afraid

3- will I get back to the days of very strong erection or it's impossible because I was relapsing a lot ?

4- Is consistency on these positive things will help me to detox my brain faster and be able to get good strong erection after 90 days ?

5- Will I be able to get erection to real women after 90 days?

6- Should I isolate myself till I finish at least 30 days or it's wrong to isolate myself?


I'm sorry but I'm really anxious, afraid, so irritable with zero self-esteem and self- confidence. I'm even started to plan my suicide but I'm afraid.

Sorry for my bad English if there any problem.
