I am semi-qualified to help out! (I have a bachelor's in psychology, so really I know a little bit but I'm not really qualified at all). Here are some questions and thoughts. You don't have to tell me the answers, but I hope they at least help you think.
1. Are you depressed because you're not training, or are you not training because you're depressed?
1A. If it's the first, and you're depressed because you're not training, then you need to actualize. You have your real self and your ideal self. Right now your real self isn't training and your ideal self is. One option here is that you can kick your real self in the caboose and get back to training. That takes away the tension.
1B. However, maybe it's possible your training schedule doesn't match with what your life can afford. If that's the case, then you need to adjust your ideal self. Maybe you take some time off and go in when you can. Or maybe you need a different school that will match your schedule or meet your motivation. It's possible you've just been too busy to train this month, and you feel guilty when you shouldn't. You should definitely make an effort to get back, but if it doesn't happen, then don't feel bad.
1C. It might also be that whatever art you're taking or school you're going to just isn't jiving with you right now. Maybe you need to mix it up. I'm going to guess you're doing Kenpo (based on some of your other posts). Maybe it's time to try something else?
1D. Martial arts can be a very good anti-depressant. They get you moving, and you quite often get to hit things or throw people, which can be cathartic.
1E. If I was wrong in 1A, and you are not training because you're depressed, follow the advice and go see a doctor. Not a bachelor-in-psychology.
2. If "today is the day" make it be the day. Force yourself to go. If today is the day, don't let tomorrow be the day. But, as I said above, if today won't work, then don't plan on today. In that case, plan on tomorrow.
Let me put it this way: if I have no plans after work, then today is the day. But if I have my nephew's birthday after work, then tomorrow's the day. And I commit to that.
3. There is no such thing as a hardcore alcoholic. There's alcoholic and not. Forgive me because it's been a long time since I studied this, but it's not about how much you drink. It's about how your body reacts. Someone can drink every night or get plastered every weekend and not be an alcoholic, but someone can go for years without alcohol and touch one drink and instantly relapse.
3A. Alcohol is a depressant. Now, contrary to how some read that, it doesn't make you depressed, but to a degree, it does calm you down. (This is compared with a stimulant, like caffeine, which brings you up). So if you go home and have a few, this is what you may expect:
- Loss of energy, less desire to go train
- Loss of self control, less motivation to get out and go train
- Not able to legally drive to go train
My recommendation is if you don't think you're an alcoholic, save the booze until after class. If you do think you are an alcoholic, that would be an opportunity to go to AA or go to a doctor.
