I so have to get caught up

I forgot that today was Thursday. As such, I forgot to spend today getting caught up on my shows. I'm two, no three, eps behind on Supernatural, muchly behind on Veronica Mars, massively behind on Smallville (like, a season and a half, I think), and my behindness on One Tree Hill resembles a nuclear (say it five times, really fast, Mr. Bush) explosion, or the after effects anyway.

Looks like tonight will be another night of no sleep at all.

Oh yeah, and I really need to spend tomorrow morning getting together the paperwork I need to find out if I can get financial aid to help me go back to school. What the HELL was I thinking that I could do this? I'm so not smart enough for college. I knew that when I was 18, what made me forget it? Plus, this being finals week and working with almost all college students? Not helping with the fear that I'm going to fail miserably and be laughed, or thrown, off campus.

And, to top it all off, I was told I should look into scholarships for students who return to school LATER IN LIFE!!!!! Do I look like I'm on my deathbed or something? I'm only 31. I'm also completely terrified because I am not smart!!

*cries*

A little technical help, if you please?

Does anyone out there know how I'd go about changing a file extension? I know sometimes, if I don't have a program that works for that extension, it'll show up as part of the file name, such as "filename.ppg".

But what about when it's something saved as a .doc, but I need it to be a .avi? The file only shows the filename, no extension, such as "filename" It doesn't even give me the option in the properties menu.

Help?
