I think you should study more and nearly stop playing. Your message
tells me that you don't know enough about the game to be playing. For example, two months is not an amount of poker, it is an amount of time. These may seem similar but they are not. In two months someone might play 1000
hands, or someone might play 200000 hands. $850 is your loss, but that doesn't mean anything by itself. I know you are not playing $500/$1000, but if you were you would have loss less than 1BB. If you were playing $2 buy in NLH and lost $850 that would mean you are basically doing everything wrong.
Because you didn't understand even which information tells people you are doing well or doing poorly, I would focus on reading a poker book, and playing just a little that you can easily afford to lose.
Like me, you probably don't want to spend money on a coach, but like me, you probably should. When $850 is a lot to lose, spending $100-$200 on a coach seems a little like losing more. However, you will continue losing money. Almost certainly you are not going to start winning next week. So, if you expect to lose another $1000, I think you should get a coach for $50 or $100 for 1 hour and see how you feel.
The smart choice would probably be to:
1. Switch to $5NL or $10NL if you want to continue to play. If you can't win at $5NL you can't win at $10 or $25 or $50.
2. Read a poker book which will cost you prob $20-$30
3. Make sure you are doing everything that the book suggests. Chances are you are not going to have any better ideas that what is in the book, even though you will think you do.
4. If you are doing what the book says, now you should be winning at $5NL.
5. Now, move up to $25NL and play a few thousand hands. You should be winning a little or close to it. If you are losing a little, that is okay.
6. Send you hand history to a coach and pay them for 1 hour to go over your hands and get advice on how to improve.
7. Follow their advice.
8. Follow their advice.
9. Play another few thousand hands and see if you have improved. Did you win more? Did you lose less? Do you know why?
10. Meet with the coach again. Focus on the changes you have made. Did you successfully make those changes? If so, then work on another thing to improve. If not, repeat from 7 until you are willing to take the advice of the people you are paying to give you advice (either you take their advice, or you get a new coach, or you stop coaching- no point paying for coaching and refusing to do what they suggest)
