Does the jealousy, the pain, the feeling of being broken ever end?

My husband and I TTC #2. Our son is going to be 9 in the spring and all we want to do is have another child.

May 2015 we found out we were pregnant... Everything seemed to go fine... Then I had small spotting... June 2015 went in for our 8 week ultrasound... Our baby measured 6w2d with a slow heart beat. Waited 2 more weeks... Our baby had stopped growing and the heart beat stopped at 6w2d... We must got to say hi the same day or baby passed... I cried for days and stayed in bed for a week...

Finally feel like everything's going to be OK. Dec 2015 I went to the ER with horrible side pains.. Thought I had another infection, that I had previously had. Well found out I was pregnant. My levels were low so they thought it was very early on. Got them checked 2 days later, and they dropped dramatically. Chemical pregnancy...

Now I am thinking, a month later... I'm OK... I understand... And then a friend announces her son...whom is her 4th biological child... But she also has custody of her niece and nephew... And my heart sinks again.

Does the pain ever stop? Or will I just learn to grit and bear it and pretend to be happy..

Sorry for so long, but needed to vent and even though my husband listens, I don't think he truly understands the pain...
