Let me first say that I'm sorry you had to have the surgery and hope that you are recovering!
I was just recently diagnosed with PCOS and it was extremely emotional for several reasons. First, I was worried about the possibility of not being able to have children. I felt that since I'm single, would this prevent me from finding someone if I might not be able to have kids!? (So silly but it emphasizes how emotional I was.) I also was concerned about my health for the future. It was all very overwhelming at first and a little scary. I didn't even know that I could have it, autoimmune diseases (such as thyroidism, lupus and RA) run in my family, for the past 15 years I thought that is what was wrong with me. If only I had known when I was a teenager that I had PCOS!
Also remember that PCOS is not a death sentence! You haven't been diagnosed with cancer or something else terrible. Yes it sucks but avoiding a diagnosis doesn't change the fact that you have it (if in fact you do) and it only prolongs the symptoms you are having. Being diagnosed, although very difficult and bittersweet was the best thing that happened to me.
I always thought I was just really moody and couldn't figure out why I was always so depressed. Before I went on birth control, I had periods that would last for 14 days sometimes, I would go through two boxes of super tampons and two boxes of regular just for one period! By the time I got to college, my PMS was so bad that I had flu like symptoms for the two weeks of my period making class and working difficult, forget having fun. Reading other women's stories on SoulCysters.com helped so much for me to realize that other women were experiencing the same things. I didn't feel like a freak anymore or that I was weird. 'Symptoms' that I had for the majority of my life suddenly made sense.
I also was always frustrated that I could never lose weight, no matter what I did. Now that I'm on medication, my life is very different. Even though I was recently diagnosed, things have changed dramatically and quickly and life is much better.
Yes it is scary and it sucks having PCOS, but not finding out doesn't do any good for you to get well. You should want to rule out everything to find the cause of these problems, whether it is PCOS or something else.
