Hi rosepetal,welcome to the forum,so sorry you're feeling so low,think a lot of us have been there,a few months back I couldn't see an end in sight but it did pass,like ladybt said,we are all so different,ad's are great for some,for me?not the case but I'm not knocking them or hrt,which I also don't take,it really is trial and error to find what is best for you,have you tried the Bach remedy drops,they did help me a bit and a lady on here recommended Benadryl,the acrivastin one a day,so there are lots of things to try.
Make sure you check your breasts every month and get to know every lump and bump,cysts are so very common but usually not dangerous.
You're not alone here,we are all way to anxious and there are many threads you can read.
Good luck
