Agree with andymoe. Don't let your current emotional state dictate your decision. Take time to think about it, talk it over with your wife, etc.

My best advice is to try and get something going while you currently have a job (you said you have time to learn right? why not use this time to build something?)

I once reached out to Seth Godin for advice on whether I should try and get a job in tech or just run with the startup idea I had on my own. He told me to quit and start immediately. In retrospect I'm really glad I didn't go with his advice since I would have felt completely lost and unprepared after the initial rush of doing my own thing. Instead, I've worked on side projects in my spare time, and eventually one idea clicked and the company is taking off (feel very fortunate).

Go with your gut, but also make sure you feel in control of your life and have options. Stick it out, save money, and if you do quit, you will be more comfortable supporting your decision as well as your family.
