You need to stop building things you don't enjoy building and which you have little to no interest in actually using. After that take as much time as necessary for something to strike your interest, possibly in a totally different domain (e.g., embedded systems instead of CRUD crap).

Once you reach that point tinker a little, not a lot. When you feel resistance take a break, never force yourself. Don't force yourself to write code you don't enjoy writing, find ways around it, at least initially. You need to avoid reinforcing the association between code and pain until you have a buffer of good experiences in your new domain.

It might be (probably will be) necessary to find a new career path in the meantime.

Good luck.
