Honestly, you sound very burnt out. You went straight through 3 failed startups and then a masters program with the goal of getting into a FAANG? I have to imagine you were only grinding to get into a FAANG for the money, but you already solved that issue. And master's programs can be quite demanding. Take a semester break from your grad program immediately and do some traveling. Don't look at a computer for anything non-essential for that break. Your motivation will come back. You've just been grinding for way too long, and it paid off. Just not the way you expected. After a semester spent recovering you'll naturally get back into working out and eating right. You just need to stop staring at a computer for a bit :)
