Pokemon symptoms and conditions

I'm 23 and I got prescribed Yasmin because I have PCOS, where I only got my period every 3-9 months (very irregular) where I suffered severe period pain and my period would go for about 8 days. The doctor thought regulating my period would decrease the pain, which it did. My period is around 3-4 days, very light and no pain since starting Yasmin. But I have had migraines weekly, constant headaches, usually starting with my vision going blurry and seeing flashing white light. I also lost my appetite for the first month, but have gained weight. I was going to the gym and exercising everyday and now I have no motivation to exercise at all, but feel bloated ALL the time. I have had trouble sleeping since taking it. I suffered from depression and anxiety attacks about 2 years ago, but since taking Yasmin I have been feeling very depressed and had several anxiety attacks, although the anxiety has only started after being on it for 4 months. After having another migraine this week and having to leave work for teh second time in 2 weeks, I decided I was going to stop taking it. (I had also had 3 anxiety attacks this week) since stopping I have instantly felt relaxed, no anxiety, and I no longer feel depressed.

After suffering all of this for 4 months, 8 day periods and 4 days of being in pain doesn't seem so bad. The depression and Anxiety is the scaries part as I haven't experienced it for so long, and don't want to!

Does anyone know how long it takes to be fully out of your system? I just want to get back to normal weight, moods, energy levels etc as soon as possible!
