I dont play full time, but i log enough hands to be able to relate to about everything in your OP. Theres a few things here i would like to point out.

1.) You can make a good living with less emotional stress at the 30-60 games. It can be worth it to sacrifice a little EV to make poker stress you out less. The time you are not playing should be your time, poker should not monopolize your thoughts.
2.) You don't sound like you want to do this forever. This is fine! But make sure you know what you are going to do when you dont make poker your primary occupation. You don't mention your age/education, but be sure you have options outside of poker.
3.) Lastly, dont let results influence you so much. Sometimes you take chances and they dont work. If you end up in the negative for October, it doesn't matter. If you play winning poker, you will have a losing month here and there and make eons the rest of the time. Don't get to stressed out over it.

Good luck!
