dermoid ovarian cyst, seeking help

Hi everyone, My husband and I have been thru the ringer lately with my body and I just really am seeking some kind of way to help myself cope. I haven't had a period in about 2 months and I was expecting to see a baby across the sonogram screen and instead I saw a huge dermoid cyst that has been growing on my left ovary since I was born. I am absolutely terrified and disgusted at the same time. He fears I don't have a left ovary anymore and he will have to remove it, and I'm scared I won't be able to conceive or it will be nearly impossible to do naturally. I also found out because of the cyst I have an infection and I'm having to insert cream which is also disgusting. I'm scared my husband won't want anything to do with me sexually anymore and that he won't even want to have children with me anymore. I'm just really needing some closure. I'd love to hear from anyone who has experienced this as well.
