Nexavar...and help with a support group online?

My step dad has liver cancer and since there really wasn't an option of surgery to remove the tumor, the doctor said he could "try" Nexavar. He him to try it for a few weeks to see how it helped him. His platelet count came up to normal range after being on it for a week, so his doctor told him to continue. The only problem he got really lethargic and sick from the drugs side effects. His doctor also talked about risks with the medicine and one included hemorrhaging. This morning that happened, he hemorrhaged and he almost died. He was projectile vomiting blood and it was so scary. So, I was just wondering if anyone else had a bad reaction to Nexavar. I know anything "could" happen, but it's still scary. Also, I'm so new to all this cancer stuff and seeing what I saw today really really scared me. I've never seen something so bad in my life, do they have any online support groups for cancer victim's family?...I'm sure they do, but could someone point me in the direction of a good one. Thanks.
