LONG POST, BUT PCOS SUCKS

Okay ladies, I am in constant sadness. I have wanted a child for months now. I have a wonderful five year old step son who I adore, and will be adopting, but I get so sad and upset with myself sometimes. Mainly because, I want to have a child that is biologically my own. I was diagnosed with pcos at 16 years old. I didn't fully understand, other than the doctor saying, "your chances of pregnancy without assistance, is slim to none, ever." That has stuck with me. I am in constant pain, from my periods, when they actually decide to show up. I am overweight, my hair is super fine, I feel hideous. I have been on a diet, and lost nothing. I am trying so hard. My husband said he will love me regardless, but I feel like less of a woman because I can't give him a baby of our own. I get so jealous and envious, because everyone I know is pregnant, or so it seems. I'm not asking for a pity party, I'm simply asking does anyone else ever feel this way? I just get so discouraged, everytime I see that BFN. My husband is my biggest supporter in life, and the best husband, he always says, babe it will happen, we will have a baby, but I cant help but feel like I'm never going to be able to do that. I'm sorry for posting such a long post but I have no one to vent to besides my husband and he hears it all the time.
