Getting Pregnant

I have been with my boyfriend for almost 10 months now and recently found out I have PCOS we had been TTC since we got together and nothing was happening (his sister just had a baby and my brother is having a baby soon also) I am 23yrs old My Boyfriend is 24 and Fit and healthy but since getting my diagnosis I have been depressed and my anxiety has got a lot worse and as I had a miscarriage at 17 it is making me worry about the stress of getting pregnant and if it will happen again (PCOS is a higher rate for miscarriage) I have spoken to my boyfriend and he is so supportive and I know he will be there for me no matter what but I feel very alone and am losing sleep which is affecting our relationship and also causing me to distance myself from family .... I feel so lost and don't know what is best to do if I should go ahead with fertility treatments or if it will make my anxiety worse I am desperate for a family of my own and just want things to be perfect for me and my boyfriend but don't know what to do for the best .... please help
