Anyone else feel alone??

Sorry in advance, this may be long.

So my hubby and I have been ttc for 7 months. I had one chemical pregnancy in June and a missed miscarriage end of August. We had all the fertility testing done during my cycle in September and there's nothing wrong (other than my age-I'm 40) we just need to wait for a healthy egg. So, we continue to try, however this has just been devastating for my husband. (I have 3 older children, he has none) So, at this point, my husband doesn't want to know if I'm pregnant until a heartbeat is confirmed because he doesn't think he can handle another heartbreak, which I understand.

The reason I feel so alone is because during all of this, I found out my 20 Y/o daughter is pregnant and due in Feb. Then, I found out in June my one friend was pregnant, she already delivered (she was afraid to tell me, then told me after my miscarriage) my best friend has gotten pregnant and 4, yes FOUR of my coworkers have found out they're pregnant in the last 4 months. I feel like I'm struggling alone and can't confide in anyone. Everyone around me is happy and showing off their growing bellies. I am happy for them and I LOVE babies!! I just want to give my husband his own, and every month it doesn't happen I have a serious breakdown where I really don't wanna be around anyone. It's hurting my friendships but emotionally it hurts too bad to spend time with someone who is living my dream....
