How am I supposed to handle reality?

It's been one of those days. The ones where I'm melancholy and a single thought about my dad's cancer can make me burst into tears.

He told me today that he's had cancer for two months now. They didn't catch it at first, but now they know for sure. He also said that he hadn't planned on telling us, but now that his hair had started falling out, he went ahead and let my 12 year old sister and I know what was happening.

Right now I'm on the vicious roller-coaster of "Oh it's going to be fine I can get through this" to "Dear God what the hell am I supposed to do?". He's had health problems since I was a small child and I was always able to handle that. Even when he had surgery to put an implant in his heart, I wasn't this emotional. Even during all of his heart problems, I was able to manage. But now that I know he has lung cancer, I'm prone to bursting into tears at any given time (I'm fighting back tears as I write this......well screw that, now I am crying).

I don't know how I'm supposed to handle this. I don't know how I'm supposed to live my day-to-day life without getting depressed and overwhelmed by the reality of this situation. My dad, the man who's already had at least two heart attacks, has congestive heart failure, skin cancer, and a physical disability now has lung cancer. How am I supposed to handle that? I don't know what the outcome of this is going to be, and that really, really scares me.

I'm trying not to let the stress of this affect my writing. When I was younger (14 and 15), I used writing as an escape to keep from getting overwhelmed with depression and SH urges. Now I'm trying to use it to temporarily forget what is happening to my family and I.

I don't know how the next few months are going to play out. I'd like to hope that I somehow figure out how to get a grip on my emotions and continue to function like a normal human being instead of giving in completely and becoming dysfunctional. But I'm the oldest of my siblings and I have certain responsibilities. I don't know how to handle everything that happens in my "normal" life and still accept the painful reality that my dad has lung cancer. I don't know how I'm going to be able to focus on dance when it starts again in August, not knowing if my dad will make it to all of my performances.

What am I supposed to do?

Cancer

*** This is a rambly post because I'm still very emotional right now. I'm sorry if it comes off as whiny, but I'm not in the mood for politeness and coherency. ***

Since April, my dad's been "sick". It's not unusual for him to get sick considering how weak his immune system is, but this time he didn't get better. He only got worse throughout the month and through May.

Tonight (well, this morning since it's 3 AM) my mom told my 12 year old sister and I that my dad has lung cancer and is currently going through chemo.

It didn't "shock" me at first. He's already suffered through two heart attacks, has congestive heart failure, and skin cancer. But as she got to talking about it, it finally started to settle in. My dad has another cancer, and this time it's more "severe" (he's had the skin cancer since I was little but it's never been too big of a deal for us).

Darn if it isn't already enough with what he's currently suffering from. As if these last two months haven't already been physically and mentally stressful enough on me.

I don't know what to do right now. I knew something was wrong more so than usual, but I didn't think he had cancer. I mean, what do you do when you're told your parent has another cancer? How does one even process that?

Part of me has a feeling that this knowledge of his cancer is only going to stress me out more. I don't want to slip back into a depressive funk. Been there, done that, it isn't fun. I don't want to be depressed to the point where I cannot function and write. I don't want to be depressed to the point where I'm snapping at everyone and withdrawn.

But how am I supposed to process this and keep my normal routine?
