There needs to be better mental health programs for startups to prevent this. There also needs to be business management training to avoid problems and find the right way to run a business.<p>Too often startups try to be the next billion dollar industry, the next Facebook, Zappos, Apple, Google. It isn't always possible. Just have a passion for what you do and do it the best way that you can. If you make mistakes admit to them and learn from them, even ask for help with them.<p>I have a mental illness and I've known mentally ill people who bottled stuff up until they killed themselves. Don't bottle stuff up, deal with it and seek professional help. If you have to ask if you need to see a doctor, you most likely do.
