I don't know man, there was a time when I blamed everything wrong with me on weed. Then, I grew up and realized that I had problems without the smoking habit too. The only way that life lesson could happen was for me to quit weed completely for a few years and seek treatment for my problems (or to see if I would get better over time, but actually I continuously worsened). The idea was to see what I was like without weed. Plus, I was smoking compulsively at that point so I had to stop anyway.
It never went away, the bad moods, lack of concentration,... even after a good year or longer. It turns out that I just have trouble concentrating, and weed helps that (in moderation). It turns out that I am severely depressed and weed helps mask that. There were other problems such as panic attacks that surfaced which I didn't even know I had before. It turns out that pot has pretty much nothing to do with anything whatsoever, it bears no impact on any of my issues except that it really helps with my depression and digestion. And just leads to a more chill mentality about life somehow. I don't feel that I need a reason to smoke it. It is just something that I smoke, and do not plan on stopping. Like how my dad drinks a couple beers at the end of the day and would probably be moody as hell without that. Just like I do not plan on stop drinking kombucha because I love it way too much.
I now smoke and vaporize weed as much as ever, and I can honestly say it doesn't really cause me any issues except financially. I'd prefer not to pay so much for a plant, but when I used to think weed made me anxious and depressed... turns out I'm just anxious and depressed as fuck. Mental illness can surface later in life. For myself it was triggered at 25 but there were so many warning signs.
Sure, I'd be moody as fuck if I came home from work tomorrow and didn't smoke a blunt. But I was like that before I started smoking again. And anyways if I wanted weed I would go out and get weed and a wrap and smoke a blunt. I just don't see it as a problem at the end of the day, or even a few times a day (so long as it's not like compulsive and distracting IMO). Especially since now it's like cigarettes here apart from being at work or driving. I hold a high level position and I was baked throughout my education and training. I work after dabbing as much as possible and it is all cognitive stuff. Stoned or not, I'm the same person with the same shit going on. I don't even know if I'd recommend quitting because if you are susceptible to 'withdrawal symptoms' (believe me I know they do exist for sure) from cannabis, it might not be worth stopping because you might end up on some kind of pharmaceutical wishing you were still a pothead.
I was brought up to see weed as the devil, so when it started helping me with my problems I had really confusing thoughts for a while. At the end of the day, I can honestly say that it really doesn't do shit apart from give me euphoria, relaxation, meditative and analytical thought... depending on the dose and grow. If anything, just the fact that you making a struggle out of it shows that, at least during this time of your life, you can't handle it. When I was 20, I couldn't handle weed either. I stopped for a long time and now I love it more than ever since I know it helps me medically. Sorry if this comes across as too know-it-all but if you are only smoking weed twice a day, and having those effects, it's just not the weed man. Maybe if you were smoking like an ounce a week at least or something... but twice a day? I would hardly even notice that unless we are talking big sessions. In my opinion the drugs are never the problem though.
This is my honest advice: slowly ease yourself back into smoking more weed like you were before, or switch to vaporizing cannabis concentrates. It's going to be legal in the near future almost everywhere. It probably helps your anxiety to use it a lot, and if you didn't you might use other drugs all of which are much worse for you. You might have an anxiety disorder that weed helps and it's way way way better to keep on the dope than go on something like benzos (xanax, etc) for that. If you start having panic attacks or some shit dude it's just REALLY not fun and it gets triggered by stress. My panic disorder came out when I quit a heavy weed smoking habit cold turkey and had a psychotic break. Looking back it was a really stupid decision to do that having so many health problems and having been smoking so much for so long, to just go cold turkey like that. Huge regret. There was a lot of pressure from external forces who for some reason had a real big problem with me smoking the herb though. Weed to me just means so much now I'd never stop, to me it is a start to the fight for personal freedom and the right to legal access of all 'controlled substances'. It's fun to smoke it everywhere just to annoy people. I mean, it's retarded... everyone gets drunk as fuck, and I do my best not to judge that although it stands against everything I believe in.
