Huh, thanks for replies. I had the walk, drank some more, I met some friends .. which was really nice afterall. I scheduled myself a meeting with a professional, even though it's gonna cost me some.
Your input is gonna help me to avoid cancelling that meeting. Thanks. Sorry that I can't do nothing about the alcohol.
Also, thanks for pointing out that no-one here can undo my depression. Kind of figured out that myself, but it's good to be backed up by other opinions as well. Few years back I would rather have had internet drama about this, not a solution. But yeah, two days I can manage.. and meet that man then. Oh wait, three days.
And also.. kyuuei's suggestions seem okay. My wife suggested similar kind of stabile activities to cut down the depression: regular sleep cycles etc. I had also considered about drinking or exercising. I do both atm - perhaps I should continue exercising, even though it seems useless right now.
If I were just able to find good food to eat. I'm not sure if any regular food works as an anti-depressant. Vegetables and fruits feel fresh and give you a nice feeling, but if you (I) don't eat fatty foods, there's gonna be hunger and tiredness nevertheless. I'm not sure what kind of food would help me.. but somehow I feel I find instant comfort from eating foods that aren't good for me, but I'd have to find how and what.
And yeah, I'm sorry for bringing this up here. I'm just tired of all this.. and all the . everything.. for two weeks now. And no, I'm not a guru who can perfectly self-diagnose myself and by my own astronaut and whatever, as someone suggested. I'm just trying to find best explanations for everything and following the leads. Depression is my best guess.
I'll fill my next 2 days with some activities to dismiss my feelings of emptiness.
