How do I get back on track?

I feel my life derailing a bit. I had everything together and now it is just starting to fall apart again. In October my dad ended up in the hospital for a month. In addition to the stress it also crazy screwed up my schedule because my family is my childcare. my pregnant sister couldn't watch him and my mom was at the hospital.

Since then things haven't been going so great. I ended up failing a couple of classes because I didn't withdrawal in time. I haven't been able to organize and remember my schedule. I have missed and rescheduled so many appointments in the past few months because I just can't keep my schedule straight. I was doing really well with money and all of a sudden it is like I forgot how to manage money. I can't get my room clean. I have been trying to 2 months to rearrange and organize my room but I just can't get it done. I feel like crap emotionally all the time and that just isn't me.

What do you do when your life started to feel like a mess. How so you reorganize and restart? I want to move out of my parent's house but I can't if I can't stop this nonsense.
