Find another job and then quit for sure and you will get a raise.

It sounds like you already know what the issue is. It will not get better.

On the other hand, you should work on yourself and examine what you can do better (as opposed as blaming you for when things went wrong ie. you snapped at somebody etc).

I would not work on weekends, like, just don't do it, let them hire another dev if they need it.
