how to know when you're in/out flatline?

what's up everyone,

I've been going through a tough time as of late. I believe it's a lengthy flatline. I began to feel like this in January and it's still kind've lingering right now.

A little bit about my reboot journey before I get into depth with my post...
I started hard mode in mid September. since then I've yet to watch a porn video, but have masturbated several times (first relapse was in November). I really owe a lot of my troubles to masturbating to early. damn I wish I didn't. I felt like I was cured, got cocky and a little carried away, and it caught up to me. at that point I felt so much self confidence, I wanted a relationship, i was unleashing my inner charm that has been hidden for so long and I was talking to girls like it was nothing, no anxiety. I was also getting morning wood almost everyday, and spontaneous erections. it also took a record breaking time to ejaculate when I first masturbated again (very quick lol). however, I didn't have sex, only a few makeouts at the club. but I was very happy with what I was seeing progress wise.

then the relapse... didn't do much at first, but it slowly began to escalate into the chaser effect all the way thru December and Jan. then I started noticing it was taking longer to ehaculate, and I had to start fantasizing again. thank god I didn't go far enough to watching porn. but I think it was just as bad for my brain, and progress.

then, bam! New Years came, this new found confidence I had disappeared and so did my libidio. man, it's almost like I've been a-sexual lately. I still know when a girls hot when I see one, but I just have no desire for sex. I haven't been out to a club since New Year's Eve. i became depressed from January thru feburary. no libidio = scary shit! then I started getting hocd back. I must admit, it's not as bad as it was before I started the reboot. but I hate that it's seeping it's way back into my thoughts. It had disappeared along with all my other anxiety!

I just wanna feel that tingly feeling when i see a beautiful woman again. I just wanna be able to get hard as a rock spontaneously when I see some yoga pants. I want that confidence and lack of anxiety back... this is frustrating me because porn has been out of the picture for way over 100 days. the only relation I have to this downfall is masturbation. I feel like I'm at square one again!!

p.s. I'm 19 yrs old, had sex with one woman 3 or 4 times, about a year ago. had ED.

last masturbated 4 days ago to try to get out of flatline.

has anyone been in a situation similar to this?

any advice for my predicament?
