Does anyone else with PCOS feel like this?

Hello

After a trying to get pregnant for nearly 2 years and having no luck, a number of blood tests are now saying it is likely PCOS. 

I am currently underweight rather than being overweight, my hair growth is quite rapid and my periods are all over the place!

I am finding that when it is 28 days after a previous period, however long or short it was, instead of another period starting I get about 2 weeks of feeling terrible! Tender breasts on and off, nauseous feelings but nothing too extreme, lots of cramps in my lower tummy, back and hips. I also find that after about 1.5 weeks of this, I feel very very tense in myself as if I have a pressure building up in me, adding to the bad moods, which usually results in me having a mini breakdown where my husband isn't sure how to stop the tears. Sometimes once this is over I will, without warning, about a week later get a period then other times nothing happens. I had a 60 day gap between cycles last time! 

I currently have no motivation to do anything (my house is becoming a skip!) and seem to be in a bad mood an awful lot....

Does anyone else with PCOS get similar feelings? No one else I really know has had it to discuss.

Thank you
