Hey man, I'm sorry for you and your GF's situation. It is really hard getting through hard times like this, but think of the fact that it's something you need to get through - life works this way. It's unfair and evil, but there is always a way up the hill.

What I'm saying is I know what you mean. The last 3 weeks have been the worst of my entire life. Saturday, 21st february, I attended one of my best girl friend's mom's funeral. She too died because of cancer. Some days before on of my best buds, who also is the boyfriend to the now mother-less girl, got bad news too; his mother were also with cancer. The same type that killed his girlfriend's mother. Very hard situation, also for me.
But it doesn't end here, eventhough I would have begged it to if I knew what was going to happen. When I came back home after the funeral after a long drive my little brother met by the door - and he was crying. My grandmother on my father's side was dead, by heart attack. A difficult day just got worse, and my story doesn't stop here.
My granmother's funeral found place on the following thursday, 26th february. The same day my other grandmother on my mother's side had been hospitalized for 14 days. On the 15th day, the day after my other grandmother's funeral, she also suffered a heart attack. My family was in chok. She survived after the heart attack, but only for 2 more days. I was in the hospital this sunday when her body gave up and slept in. Her funeral was yesterday.

Sorry, if my story was too much. I'm just trying to say that I know your situation, and I just felt like writing it somewhere. You feel so down, because all this just drains all your strength. But I'm trying to keep my head high. You should always keep your head high.
I know it's hard to cheer up your girlfriend. I know it's hard being in this situation. But the important thing is not how you cheer her up, because sometimes you can't. The important thing is that you're there for her. Just being there is enough. Happy times will come again, it just takes time. Patience, my friend.

I hope you'll be alright. You and your girlfriend have my sympathy and I'm sure you'll both make it through.

Best of hopes, yours sincerely a stranger from Denmark - and sorry for bad English.
