Let us put it straight.
Understand the difference between distress and depression
You simply have distress because you failed in on situation,just one situation, and you are worried.
You have talent and you need to understand it.
To understand yourself is not a big deal.
We do face tough situation often, We do change everyday, and we change for good.
We learn from experiences not to lose again.
You had one experience and next it will not happen if properly planned.
Plan and execute.
