i want to know my current case.

I'm 25 years old, i was doing PMO since i was 11 , in the last 3 or 4 years i started to watch more more more intense porn. and this intense porn started to be more frequent in the last year. in the last few months maybe 4 or 5 months i started to suffer to maintain erection during PMO. currently,
I'm on day 4 on no masturbation
day 13 of no porn.

I'm having weak erection during sleep and once I wake up it disappears. most of the time i feel my dick sleepy and shrinked although i when i see a beautiful girl i feel i want to have sex with her but i don't fantasize her or any other girl and i don't feel anything in my dick.

note: i had multiple streaks within all of these years but i finally reached to point i can't accept to pmo again

i'll get married after 5 months from now and i'm diagnosed with BPD and OCD.

so,
do i have PIED ?
is the period of 5 months enough to cure my pied ? especially if i exercise regularly and taking different supplements as ginseng and multi vitamins
am i in flatline now ? or it's only the pied. because i feel everything is messed up and don't know anything anymore

 

i know there is no such a thing but i feel it becomes more smaller in the last few days (which means after)
