Scared

I'm 27 and I feel like my window is closing in. I've known I had PCOS since I was about 14. I know I have to go through a fertility dr in order to get pregnant and I have started the process, but I am so scared. So many things run through my mind. I use to put having kids off for school, new job, new vehicle, new apartment etc anything to ignore that fact that I am scared out of my mind. My sister has lost two babies and the pain from that had me depressed for year. I'm scared that I will never be able to get pregnant or that I will not be able to carry. I'm scared of falling in love with my bundle of joy and then having my love taken away. 😔😔
