Falling deeper into depression...

I can feel myself slowly going back into depression, I had it before pregnancy and on and off since my son was born. My son is 8 months now and the sweetest little boy, but even with him I still feel depressed. I got better when I joined  a women's league of Rugby and I loved it, I was happy and getting in shape but my husband wasn't crazy about it. Of course with my luck I fractured my knee over a week ago and ever since I've just been getting more and more depressed. I tried talking to my husband who knows about my history with depression and he just blew me off and ignored me which made it worse. The bad part is I don't even care anymore, normally I pull myself out when it gets bad but I don't even want to try. I don't know how I let it get this bad but I'm hurting and I have no one to go to especially my husband.
