Confused, afraid, slightly angry and I don't know what to do. Need insight/advice.

If you want the post with more detail that I made on Reddit, ask me and I'll DM it but I want to give a short summary (as short as I can make it. lol) with this post in particular.

There are two perspectives which I guess might have individually or both caused the problem I'm going through.

1). Being unproductive - To keep it short, I'm currently on a gap year with less than two months before I go off to college/university. The gap year started around last year July and ever since then my daily routine has been pretty unhealthy in the sense that I would only watch series, watch movies, play video games and browse the internet everyday. I don't know If I have depression and although it is associated with it (Not pushing aside that I could have depression, but I want to be clear about my reasoning), but the reason I do these things are because I'm introverted and draw energy from solitude (Probably to a fault). Although my NoFap journey could be a bit more responsible for this (I'll get into it with No. 2), during the end of June or start of July this year the anxiety and depression (not clinical i think) I was having for months flared up in a really bad way and then proceeded to completely subside the next week. During this Monday (It hasn't really left me yet) I experienced a sensation whereby I felt calm and collected, but my enjoyment felt diluted.

I did enjoy this for the first 6 months (if not up until February or May given some specifics) before I burned out in May in decided that I'll hold off on these things until I get to university/college. My guess Is that my lack of productivity has left me depressed, bored and/or caused be to burnout on these activities due to the consistent repetition of my days.

2). My NoFap journey - I've always been against PMO ever since I started, but still gave into it for years. During January/February, POCD intrusive thoughts abruptly popped up into my mind leaving me distressed. I did what everyone would do in the scenario, and that was to ignore the thoughts and focus on other things. This worked for sometime but the thoughts started to pop up with far more frequency possibly because I let myself be susceptible to them due to my lack of productivity. Ever since they became more frequent, I'd be in a consistent state of anxiety and have occasional depression. This all spiked up at the end of June or start of July after a 50 day streak (give or take a few days) as i mentioned and then completely subsided after. The brain fog, anxiety and depression that I had as a result of the thoughts left me as i mentioned and then this diluted feeling I'm having set in. My guess with this is that this could be another flatline (after my 2nd), but I'm unsure and afraid of this and I suspect that It could be a bigger issue because my flatlines were caused by the intrusive thoughts but this isn't and It feels like something new.

I gave the info on my lack of productivity to include all the things that could be relevant to the problem, but because this is a NoFap site, I'd really appreciate anyone's insight/advice on that in particular because I don't know what to think of it. If you have any comments to make on my productivity, feel free to comment on it or DM me.
