How do I deal with this relatives problem?

I have been a spoil t brat during my younger days but I have really changed now.I am now married to this wonderful guy,settled in the US and life is good.I was also working but due to certain reasons I had to leave the job.My family (aunts,uncles) still see me as the spoilt kid and keeps insulting me time and again that I am not good, I am just a homemaker with no job and kids.To make things worse I still do not have kids coz I have some hormone problem and miscarried twice.I did not tell anyone about this coz I do not want to be pitied.I am applying for jobs but no one is willing to give me one right now because I am on certain treatments that requires me to take leave on and off.I am actually going through a rough time.How do I find peace with myself and relax?
