Birth control & anxiety disorder!

I first started taking the pill about 6 years ago and was regularly put on different ones to try out with lower hormones doses in. I felt like every single type I was on effected my anxiety and made my panic attacks worse so stopped taking them. I haven't been on any birth control for about 2 years now and want to find out which is best to go on without any bad side effects.. Me and my boyfriend have sex a lot and I definitely need to go another form of birth control (besides condoms!) as someone with an anxiety disorder I worry about getting pregnant a lot !! Any suggestions girls? xx
