Yeah, it sucks that I relapsed when I was so far into it. Though honestly I'm not sure how well I was actually doing, since near the end before I relapsed, I was somewhat consistently looking at porn without PMO'ing, and eventually I started edging some too, and at one point I just thought, "Fuck it, I'm getting nowhere like this" and decided to just go all the way and PMO, which resulted in a month or so of PMO'ing. I guess it is nice to start again fresh without separating PMO'ing and just viewing porn, since now I can't rationalize it with "Well I didn't MO so I'm still in the clear". Anyway, I'm at a week for no P/PMO. Started lifting heavy again this past week too; for the past maybe two months, I've only been doing some curls and shoulder presses and stuff with dumbbells at home, and now I'm going to a gym and benching, squatting, etc. There was honestly no reason for me not to go before either, since my workplace has a free gym.
The conventions I go to are anime conventions. They're a ton of fun, and a good number of the people that attend aren't really a stereotype of what you'd expect an anime convention attendee to be like. They also have a bunch of non-anime related things; videogames stuff is almost as prevalent as anime stuff, there's always a bunch of Doctor Who fans, some Game of Thrones cosplayers, etc. As for meeting girls, they can be good I guess. Kinda depends on what you're looking for. It's not too hard to find a woman to just mess around with for the night, but they're usually not too great for long-term stuff, since since in my experience it's pretty unlikely that you'll meet anyone that lives within a reasonable distance of you. The only reason I was able to meet two girls that I saw consistently was there's a relatively smaller convention that takes place about 10-15 minutes from where I live. I think the convention next closest to me is about 2 1/2 hours away. I actually just attended a convention this past weekend, which was a blast. Wound up messing around with a girl Friday night too.
As for drinking, I wouldn't say it's a social anxiety thing. I am fairly shy around people I don't know, and a few drinks does help me loosen up, but I usually only drink in situations in which other people are also drinking. I just sometimes don't know when to stop drinking, or I'll drink more too quickly before I feel the effects of my previous drinks.
Oh, and I'm not seeing C anymore. Long story short, in late September we were hanging out along with a couple of other people, she got shitfaced and started acting like a huge dick, and I just got fed up with her shit. I ran into her at the convention this past weekend, and we were civil enough to each other, but other than that I haven't spoken to her since.
Also, congrats on reaching one month!
