Omg you are so young... i am sorry to hear all your troubles. I think you should talk to your husband and tell him all... he might be able to understand and if not just hang around people you kn will be supportive... you need to focus on yourself and stay positive... My mother in law found a lump on her breast 15 yrs ago, the breast affected had to be removed but she has been in great health since... about the baby, we have a friend who both her and the husband wanted children so bad back early on their marriage they both were the only child in their family but they weren't able to conceive, so after 10 years they decided to adapt and when they did everything changed, she adapt a couple from Russia and soon after she got pregnant and the following year another, and now they are raising 4 so really happy...
mom always said things happen for a reason... i will pray for you... if i may suggest take this wknd and go to a spa and relax, have a massage then catch a movie with a good friend (someone that boosts your energy).

everything will workout...
take care
