I'm going to jump off the roof when my startup company goes down
Why would you jump off the roof?
Because of three reasons: 1. I hate my day job and can't wait to be free, 2. I'm so much in love with the feeling of jumping off a building , it's so amazing 3. I want to commit suicide because there is no other good way for me out
That is the last thing you want to do. Think about how your friends and family will feel if you do this. Your company can still survive if you try.
It's probably too late for that.
If you truly think your business is down the drain, then go get some mental help. Wanting to commit suicide is never the answer. Your life is infinitely more important than your business ventures.
