i totally understand you! I left school for 9 years, now when i went back to it, it felt very strange at the begining, but after a couple of days its all good again!
Good luck with school! I just finished nursing school two weeks ago. I went back to school as a 35 year old single mom. If I can do it anybody can. It is tough, but it can and is done all the time. Just know that some days will suck bad, but they pass. Some professors seriously suck ass, they too pass. And most important be smart about the battles you choose to fight. Most are not worth it in the long run. and be prepared to jump through lots of hoops.
Good luck!
You will rock!
