Serious issues at 21 please advise

Hello, yesterday I had surgery and they found out that both of my tubes and one ovary are all fused together with adhesions in a giant cystic mass which is joined to my pelvic wall, some of my lower organs also need separating, they said I can have ivf with just one ovary and no tubes but has anyone gone through this so young before? Is there a chance my other ovary will be ruined too by the time I have the next surgery? I’m pretty stressed about it
