Day 6: NoFap Journey

So, sidenote: I'm new to the whole forum thing. Anyway I've been taking a cold shower every day along with nofap. I made it to day 6! and I'm very proud of myself! which is great, no problem there, but last night I went to this intense Depression, which Isn't the first time, I think on day 4 I also has this issue! it seems to occur at night time! I don't generally have depression and am generally and positive happy go lucky kind of guy that tends not to many shits about issues that most people dwell. but I mean last night I was questioning my whole existence, like what is the point of this anyways? why am I doing this? Then I was getting depressed about being happy, which no sense whatsoever! also been battling insomnia. I'm also afraid that since i'm so damn horny all the time. well, that i'd be desperate for sex and do stupid sh*t.. anyway sorry for rambling.. other than this, I feel like for the first time, I can see myself becoming somebody, and I've gotten so much done since I started nofap, the productivity, holy graham crackers with Nutella!!! (Nutella is the sh*t) Disclaimer: not sponsoring that stuff.. uh.. well, I guess I'm curious if anyone has any advice moving forward? Yall have an amazing day! and best of luck on your journeys!! <3
