Is it normal that nothing works out?

the past few years have been so frustrating and have really put a strain on my life and marriage. we tried for a baby for over two years then when we finally got pregnant, i had a miscarriage, my husband and i nearly split up. we fought for over 12 months. went to marriage counseling. my therapist actually told me to leave my husband and pressured me into seeing a lawyer. i finally realised that it was my miscarriage that was causing my depression and causing the fights and the stupid way i was thinking.
then when we finally started getting back on track and wanted to try again for a kid, some asian prick drove into the back of my husbands car! he was in hospital for a few days and is still in really bad pain, this happened over 6 months ago. he is non stop getting scans and seeing different doctors and specialists and that is all they seem to be doing! thank god there is nothing wrong with his back but they cant figure out why he is in so much pain. he cant work much anymore because of the pain and it has also put all of our baby plans and buying a new house plan on hold which i dont really care about, i just want my husband to get better. i am getting sick because i am getting so stressed and my husband is too damn proud to take pain killers which frustrates me even more!
but its almost like someone has put a curse on us because whenever things start to look up for us, something happens to bring us right back down!
sorry if this is long but i just needed to get it out. whether i get good or bad comments, it doesnt matter. i just wanted to get this out there so hopefully things will start to turn up again for us. thanks for listening (or reading) xx
