Depressed and Sad

It's been an year that I had a miscarriage! After that I am struggling with doctors and treatments, trying to get pregnant again! My husband is against all of this! But he does what we have to do it! Several medical tests and vaccines! Today, he just told me that we should give up, because if it is not happening, the answer is that was not supposed to happen! For the first time, I agree with him! I am so tied and so frustrated, that I do not do anything else! He is a dificil person, not supportive and I feel lonely in this terrible journey! I am even thinking about a divorce! Sometimes I think that because of this out relationship is falling apart! I do not feel any happiness in my life anymore! I need help, I know I am facing a depression!
