Just want my rainbow baby

People are telling me that I should just give up, I just had a miscarriage back on January 14th. A friend of mine or I don’t even know if I should consider her a friend she told me that why I wanna have a baby so bad to just let it go, if I had had two miscarriages thet they happen for a reason, thet really hurt my feeling. I have been trying for almost 13 yrs I had a miscarriage back in July of 2018 and another one on Jan 2021, I just want my son to have a sibling he was so heartbroken when I told him mom lost the baby he started crying 😢 God please give me the strength I need to not give up.
