Divorce help: spousal support?

Hi. I just recently completed chemotherapy (hooray). In January I was diagnosed with lymphoma. Stage 4. In March my husband (of 8 years) moved out, after I discovered his affair. Shocking. He's living with her now and we're in the middle of a long divorce. Does anyone have advice on spousal support/alimony relating to medical conditions/cancer?

We make the same income. However, I'm seeking spousal support to help offset medical bills and hedge against a relapse (which, in my case, I am told is 50%).

Advice? Resources? Experience?

Thanks!
