TS, you need to get yourself occupied with other things to distract yourself from all the negative thoughts. Hang out with your colleagues or make new friends.

Always do that, surround yourself with positive people who inspire you and bring out the best in you.

Think of the greatness that's waiting for you in the future if you're back on track. You were there once, why not now?

Don't think of suicide, it's just an easy escape. Think about your family who cares about you and their feelings if anything happens to you.
