I just feel like having a healthy baby will never happen for us and it making me super depressed

Britney • I'm a happily married to the love of my life and I'm a 27 year old who is graduating university soon this year and is hoping to start having some beautiful babies soon! We have had one pregnancy and miscarriage at 7 weeks so far hoping for a rainbow baby

I'm having a very hard time with my last miscarriage (it was at ten weeks a missed miscarriage and I had three chemicals and one other miscarriage at 7 weeks we have been trying for over two years and are seeing a specialist) I honestly am feeling suicidal most of the time but won't do anything to hurt myself don't worry. I just feel like it will never ever happen for us and now my little sister is saying they are going to start trying (not to mention she told me this as I was crying telling her about my miscarriage) which I'm sure they will have no trouble with and will just devasate me. I will of course be happy for her if it happens but it is still extremely difficult. I just don't know how to have hope anymore all I want in life is to be a mother and will be completel devasated if it doesn't happen. I've also been through some horrendous things in my life and always thought at least I will be able to have kids easily (Becuase everyone in my family says they just have to look at each other and get pregnant) but it's not the case and noone in my life cares about how I feel or my miscarriages they just ignore me. I just don't know how to feel better about all this
