Giving up

Sami • 24yrs old lost my baby when I was 9weeks, God has blessed me with a baby boy! Due June 11th!
I'm very close to giving up. I cant take this anymore. It took me over 3yrs to conceive with my ex Fiancé and nothing. Took over 2 yrs with my bf now got pregnant then she became an angel. Since my miscarriage in DEC I been trying and nothing. Im throwing in the white towel. I just hope my love can understand how hard it is for me and not being able to look his sister who is 21 and pregnant with her 2nd baby which is killing me more then ever. Just so depressed.
