(Edit: I wrote this assuming you were talking about your startup, I may have misread the question. It probably still applies.) You have to separate yourself and your identity from that of your startup. Yes you live and breathe it but no you are not it. I was my startup and when it fell I fell. It took years to recover, multiple moves, etc. Your startup is just something you're doing. It doesn't matter if it is successful or not because the only thing that matters is that you have finite time on this Earth. If you aren't capable of doing something without going crazy and losing years and years of your precious life due to panic, then you sure as shit shouldn't have been doing it. Keep things in perspective. Success is nice, but you will learn a lot from your startup if it fails and you will be better for it. You will have a higher chance of success doing your next startup, and you will have life experience that you can't get any other way. If you do good work there and it fails, people will still respect what it was and who worked on it. Stay strong, keep things in perspective, and enjoy what you do. You cannot change the world if you can't stay stable yourself. The only way you can change the world is if you are okay with yourself first.
