Trying to make sense of it all - anon for this

I used to post on these boards several years ago when my DH and I were going through our IF journey. Just a short history of us is we tried for 6 years with countless natural cycles, 3 IUIs and 6 IVFs. All BFN. None of the IVFs were covered by insurance because by the time I starting doing the IVFs I was over 40. We decided a few months ago we were done TTC. We both are emotionally (and financially) spent. We need to live our lives. We mainly decided because of our age. I am almost 44 and he will be 46. I am still in the process of grieving and I am sure I will be for some time. We contemplated DE and adoption but our heart is not in it (nor do we have the finances).

I wanted to post because of an encounter I had with a friend the other day. It made me question life and the whole universe really. You will understand when I explain the story. It is kind of a confusing so hopefully I explain it ok.

I have a friend named (Amy) who I went to high school with. Most recently I got to know her again because she lived down the street from me. I have since moved, 3 years ago, and we lost touch again. She is a really great person. She is my age and has 3 grown boys (all in the military) and her youngest is a girl around 14. Her brother in law, Jim, was dating a girl named Brenda about 10 years ago. Brenda decided to cheat on Jim and got pregnant by another guy. Brenda is a drug addict and has been in and out of rehab all of her life. The state was going to take her baby away and Jim stepped in and became a foster parent and then adopted the baby. I give credit to Jim since it is not his biological child and the result of his girlfriend cheating on him.

Brenda in the mean time has had 3 more children all with different men. Each one of them has been taken away by the state and put in foster care. Here is where my encounter begins. Sunday I was in the grocery store and I saw Amy. It was great to see her and low and behold in her cart was the cutest 1 and a ½ year old boy. She looked at me kind of awkwardly (she knows my IF history) and I asked her who the little boy was. She said it was Brendas 5th child. (by the way Brenda is 39 years old) The baby was actually a twin and one of them was lost midway through the pregnancy. The child she had with her was born at 2 pounds and was addicted to heroin and cocaine. It was born a premie and it was touch and go for some time but he is doing well now and is 18 months old. I asked where the father was and Amy said he is died in a gang shooting. Amy has decided to adopt the child. I was floored. She only planned on being a foster parent for 2 months but she fell in love with the baby during that time. Can you blame her?

Amy and I talked for about an hour on how unfair life is and how she thinks of me all the time. How DH and I are such a great couple and we cannot have a child. Why???? God has some explaining to do we said. How can a woman like Brenda have 6 children and not blink an eye to see them get taken away?

And get this. Brenda is now pregnant with her 6th child and is in rehab.

I cant stop thinking of this. I dont know how to make sense of it. I am sure you all can relate but since we stopped TTC it just stabs me in the heart. I think I just needed to vent so thanks for listening.
