I think I may be bipolar and I'm SO scared!!

I think I might be bipola, I was diagnosed with depression when I was about 22, I became extreamly depressed where I tried several times to kill myself with tablets with only once needing an ambulance I also use to self harm. I received the coucelling and anti depression drugs etc, so for the last 10 years I have had my ups and downs but most recently I decided to give up smoking and asked to have champix tablets to help me give up smoking, after a few weeks of taking them my moods started to change, i became very tired, didnt want to do anything which i had to force myself to do things, i would snap at the smallest and sillest thing so i stopped taking the tablets about 6 weeks ago now but my moods seem to be getting worse one minute i am fine and doing spring cleaning ironing and so on and then all of a sudden my mood will change. i get paid and go and spend it instead of paying bills, i find it difficult to sleep at night i snap really quickly and one minute i will be sitting there and the next i will be crying. i really need some advice as i am going out of my mind and i am starting to scare my self with my moods only an hour ago i was in kfc with my partner and i asked for the chicken to be all legs and she came over and gave us thighs so i told her that we wanted legs and i also order a pot of beans and when we sat down i discovered it was gravy so i had to send my partner back to the counter to change it because i was just so so angry.

I really dont know what to do because i have just found out that my brother and cousin both have been diognosed with bipola and i know it runs though families.

Thank you for listening.
