How a consistent lack of sleep has affected me

So, I have not been getting much sleep. It's bad. But between the 10-hour school/work days, a several hours of homework each night, and several other things, it's kind of difficult to make sleep happen. But I need to fix this. Lack of sleep doesn't really do great things for me, or anyone probably.

So, here is the thing. I can actually function pretty well without much sleep. I don't even feel too sleepy most of the time, but here is how sleep does affect me negatively:

• I am incredibly grumpy without enough sleep. I pretty much hate mornings (more so than I would anyway) and hate other things. I'm not typically a hater.
• This is similar, but I am so very irritable without sleep. I feel so annoyed with people all the time. And the thing is that I know that this is mainly my problem, so then I feel annoyed with my irritability. It's a rude cycle. 
• I feel achy and like I just want to be lazy.
• I don't know if this is from lack of sleep, but I heard sleep deprivation can cause this problem, but I crave sugar all the time these days! What happened to healthy me? I think healthy me is still there, but wait, where are the cookies?
• I feel like my memory is terrible. Things I have known for a long time, I now have a hard time remembering. And remembering new things: good luck to myself with that! Normally I'm pretty good with names, but not so much right now. 
• I don't feel like I experience life fully. I actually still do a lot and have the energy to do a lot, but I feel like I get a little bit detached. 
• I keep feeling like sickness is coming. 

Ok, so I need to stop with this sleep deprivation fiasco. So, what am I going to do? Well, I think I want to set a goal. Here it goes. Getting fewer than six hours of sleep a night is not an option for me. You would think that this goal is not too bad, but it's actually kind of stressful to me. How am I supposed to get everything done that I need to? So, I need to remember to be nice to myself if this doesn't happen, but I also need to make this a major goal. I need to plan ahead where possible to make this happen.

Wish me luck on my sleep endeavors!
