Trip to the ER last night has me depressed

The last several days I have been in a lot of pain. Yesterday the pain was really intense, more than normal and it was up my left side, down my left leg and all across my lower stomach and lower back. I know I have PCOS and I know I have fibroids. So over time a lot has gone on down there. But since May I have assumed all my problems with pain were related to fibroids. Since the pain was increasing and more than normal I decided to go to the ER. My fear was that I had some sort of infection or gallstones or something like that. I know the pain of the fibroids and I havent had cysts in a long time. None that hurt like this since before my kiddos. But guess what...it is a cyst. The cyst is 4cm x 4cm and he ER doc said it is definitely the reason for my pain and that unfortunately it was just going to be a matter of waiting...This is sadly the same thing the dr's used to tell me when I would get cysts prior to my first pregnancy. I had somehow assumed that the days of large, painful cysts were gone. This has totally freaked me out. This means that I am going to just be in pain indefinitely and that I will probably start getting them again. I used to have horribly painful cysts. Like the kind that would have me in bed for a few days. But I cannot do that at this point in life. My job requires me to be able to get up and down with ease, the hold children, to be playful. And my kids need me to be able to function too. Anyway, I am just feeling pretty depressed about it this evening.
