First - please seek some professional help immediately - you are not alone, and these feelings are common in people who've had a setback. Perhaps there's a slight chemical imbalance in your brain that needs to be reset - but only a professional can guide you there. Perhaps, all you need is some time to reflect and unwinds. Just don't make any rash decisions that have permanent consequences.

RE: startup failing.

"I have not failed. I've just found 10,000 ways that won't work." - Thomas Edison

Having a startup fail is, in itself, a success. At least you tried and with the failure, you learn things that you can use with the next startup.

Don't give up. There's so much negativity in the news we're not seeing the positive sides of things. Technology is advancing quickly and we're on the verge of a new age. It'd be a shame to not see how it turns out.
