I feel like my vagina is so messed up

I’m absolutely terrified of what could be wrong, I have an appointment with my family doctor about it but it’ll likely take a long time to get in to see a gynecologist.

First I thought I had a vaginal wall cyst. Then it went away. Now it’s back, upon further inspection and circumstances I actually like it could be a prolapse (rectocele?) I’m absolutely mortified. I’m scared to poop even. I stuck my finger in and actually felt like make I do have a cyst in there but that would mean I’m having a cyst and a prolapse! I’ve been laying on the couch sobbing, terrified somehow this will be the death of me or ill have to go through horrible surgeries. I need to poop but I’m too scared to! I’m afraid something will fall out or a fistula will open up 😭 Am I overreacting? Please help 😭 Advice needed
