Am i in flatline?

Firstly i want to say that my english is not great,and it's the first time im posting something on a forum.
I started masturbating when i was 12,now i'm 19,i used to masturbate every two days.
I stopped masturbating for around 10-14 days in a row back in December,not because i wanted(i didn't heard of NoFap then),but because i met a girl and just didn't need to masturbate(we weren't lovers).In that period there we're days when i felt really sick and couldn't even eat.Before that i used to eat a lot of sweets but in that period i didn't eat at all.I think i lost 22 pounds in 2 months or so.I heard about NoFap in february and i decided to start it.First try was 15 days,i relapsed then and that's the second time(day 55 i think).Before nofap i had morning wood everyday,errections randomly during the day but now i barely have morning wood and not an single errection during the day.When i started NoFap,after a week,i felt so many changes(my confidence,eye contact,i felt more motivated,more happier,felt like i can have any girl in the world)but now it's like i lost everything but the eye contact power.Am i in flatline? back in december i didn't know why i feel so bad but now that i read about the flatline,i think i was in flatline back then.Now my mood changes so fast like now i am happy and after 5 mins i'm sad,i don't know why.I have no sex drive.Is this flatline or am i normal ? it wouldn't make sense before nofap to have sex drive and morning woods and now after i quit porn to have zero.You can ask me more questions if you want to know more!hope i didn't make many mistakes in my grammar.
