Help! Living with ill hubby's mother and ttc.

Sorry for my bad English. I'm 28 years old and I'm married for 4 years with a man of my life. We love each other! We live for 4 years with his 74 yrs old mother who is very ill, and can't move last 2 years and just dying now. We ttc for 1,5 years for our #1 and still nothing. Most of my friends have kids.. And my period started yesterday with 2 days late..

I know that you feel me and understand my emotions.

I'm so tired, I live like in a hospital, we are on stress every time and don't have a regular sex. I don't want to live with 75 years dying woman, I want kids! But it's different in my life..

I believe that God has His plan. But I'm less stronger that I thought, I can't just "stop thinking and don't worry".

Maybe you have a similar story?

Please, give me some courage, give me some hope ladies. I really need it.

Thank you.
