What am Igetting myself into

Now that I got this far in life with a family, going to college, trying to balance my world around me, I am finding myself being overwhelmed with it all. I have my days I just want to give up due to the fact that I have not been in school in 33 years. Single mom of two teens and just losing a job of 27 years  is now taking it's toll on me. Can't even work this stupid computer. Then I have this issue for my finances and school finances which I went by the book to complete and then you find out it isn't coming through as planned... I may have to give up all I have been striving for... been crying for days working on it... staying positive and believing it will all work out dwindles yet I never try to show it around anyone. What do I do now??? I have no clue
