Congratulations!! I know you must be so excited and of course nervous, but you will do fine.
I am 38, soon to be 39, have been taking college classes for the last 2 1/2 years, work full time outside the home, do all our finances, grocery shopping, and cleaning of the home, and have 2 children still at home. DH does cook on some of the nights I am not at home which does help. My house is not as 'spotless' as it once was, but I have grown to accept that I can not do everything and it is ok not to be 'perfect'.
I somehow find time to balance it all. My two children that are home are active in school and sports, so that takes up some of my time too, but I wouldn't miss their activities for the world. I have found out that they grow up way to fast since my oldest has left the nest.
I am lucky to work for the school district. I love it! I am the librarian at our campus and am going back for an elementary education degree with a minor in special education. Working in the field I do allowed me to make sure this is where I want to be. I worked for 6 years in special education as an aide before moving to the library position. Working for the school also allows me to have summers off and I usually take summer classes, but I took this summer off to enjoy time with my family as my DS#2 is going to be a senior this year. He will be gone before you know it.
I work Mon-Fri, 7:30 - 4, take classes Mon and Wed 4:30 - 8, on Thurs I attend DS#3's sporting events, on Fri night's and Saturday's I attend DS#2's activities. I try to do at least one load of laundry every day to keep from having it pile up. I plan a menu and grocery shop every other week instead of weekly. I do most of my homework on the weekends when I have more time. I pay our bills online and do this on Thursday or Friday when I have free time. I usually have a break at work and can get this done during break time. Of course, I do not have this problem during the summer. My children do help with some of the house cleaning. They clean their own bathroom, help with doing the dishes when I ask and the floors if I feel overloaded. I don't have to ask often, but there are times when I have so much going on that I do have to ask for help which is ok. It is ok to ask for help and you may need to do just that. Like I said earlier, my house used to be spotless, but I have learned that is not what is important to me. I can't wait until I can say that I EARNED my degree. It might take me 10 years - not really - but it sure feels like it.
Just don't get discouraged!! You are going to be so proud of yourself. You will be surprised to see that there are a lot more 'older' students than younger students in the classroom. I felt the same way until I stepped in the door and then I realized I wasn't alone.
Good luck!!
