I cried in front of a total stranger
Why did you cry in front of a total stanger?
I'm tired of everything and had a nervous breakdown in a bathroom.
Sometimes when we bottle things away, we don't have control of when they come out. Perhaps it would help to talk about your overwhelming feelings with someone you trust.
Nah, everything is fine. I'll be okay.
If you broke down in the bathroom and cried to a total stranger, it sounds like there might be more bothering you than you are willing to admit. Don't you think it might be a good idea to talk to someone before it gets worse?
