I find it quite an insult that you bandy the word suicide around like it's an appropriate response to the situation of 'no girls liking you'.
Both my father and my aunt committed suicide, and both had mental problems.
If the only reason you feel like this is your relationship status, I'm actually pretty sickened.
If, on the other hand, you are very depressed, then I apologise.
It just ***** me right off when people exaggerate about what is really a terrible thing to happen.
