Oh, I'm SO sorry about your baby. I went through many infertility proceedures that never worked, and I always thought I was "lucky" in a way because I never got pregnant so I never lost a baby. It was hard enough to lose the "plans" I had for kids. I know the pain will never completely go away, but I believe that families are forever and you will see your son again.
I did end up adopting my 2 children, and it healed a lot of the pain. My kids are TOTAL sweeties, and they are the ones who convinced me to get a kitten (took 10 years of begging.) Now I'm the one who is head-over-heels in love with Tiger. He is my little buddy and follows me around the house during the day. Sits in my bathroom sink while I get ready in the morning, lays on my feet when I'm sewing. Cats really bring a lot of love into your home.
Happy Holidays! I'm glad that you can smile and laugh through your sadness.
