I wouldn't have lasted 8 months. Seems that the job description was deceptive. You are most fortunate with having lots of savings. If I were in your situation I would quit now, begin a startup doing what you most enjoy doing and then using that as your current job, seek out an ideal job. If you choose your niche well, you could even be a micro-acquihire.
