[TDL]

If I was in your position I would begin looking for a position in another company in a similar role (it's not clear what type of projects your are taking on.) It's great that you have been provided with mentorship & support, but, working 10 hours a day is not sustainable over the long term. This company sounds like many others in consulting; get bodies in chairs, sign on more business than can be handled, and crack the whip.

Start out attending technical meetups (the language your are writing in or a topic your are interested in, preferebly both) in your locale. Build your professional network and don't feel bad about asking if a company/startup is hiring. I would also start saving every last dime in case you get to the point where you are completely burnt out and just have to quit (not ideal, but might happen.) You are probably going to have to slog through a bit more before you find an opportunity.
