It is pretty distressing that my girl friend broke up with me on my birthday,
I was suffering from insomnia for weeks.
I have no idea that how to say something upset although I feel helpless very
much.
This is my first time to come here.
I'm not good at English, so please correct me if I'm wrong.
Thank you.

I am so sorry to hear about that, you will meet a better one. if you want to describe a period, you have to use perfect tense,

To look on the bright side of your life.

There are many grammatical errors in tobedesigner's sentences as well.

Life still goes on! Cheer upb
