SInce you say you just started a few weeks ago and we have no reason to not believe you, you could be the guy we been looking for.
Let your poker mind be pliable, and take all of our advice, and read all the articles, watch the vids, and play each game or tourney with a particular article or video in mind, or a particular suggestion that you want to try out. The goal here is to internalize little bits of information and experience with each new article/game. Every article here, even the Phil Ivy interview, has some little piece of info that will add up. Pay particular attention to avoiding, from the start, any over eagreness to play a hand. Common wisdom is that you will volentarily fold somewhere around 80% of your hands. Plus or minus.
In fact, for a first assignment I would suggest you get into a play money sng and fold every hand. Not by leaving the table, but by sitting there and actually folding. You must watch the table, and try to guess what any player is playing. In the beginning this will be purely guessing, but over time, one can learn to expect what a player has in general, and sometimes what a specific player will have.
I suggest play money during the first many months of your training. Everything you find here will work at play money tables with the big exception that there are so many bad players at most play money tables that it actually throws off good decission making. It is good decission making that will bring you the most pleasure as well as perhaps a buck or 2.
Ask us specific questions. You may get a large range of answers, or you may see that really the answer to a specific question is the answer given by everyone.
Ask us general questions. These are much easier for us because they have a generic answer, 'It depends.' Bt that's because zeroing in on specific situations from a generalization is so dependant on all the available facts. So learn how to get Hand Histories, and Screen Shots and how to use this site and how to post them.
Depending on your schedule, and willingness, I would suggest that you could be playing pretty good in about 50,000 hands (totally made up guess, which tends to be totally wrong 27% of the time). In the big scheme of things that is not very many hands. But online it goes a lot faster than you might guess.
Most important might be to learn that as serious as this game can get, it is a game, and games should be fun.
As for using poker to relieve stress. That one's got me stumped. I think I would prefer drugs.........
