Very Afraid I Won't Succeed

I'm very afraid I won't get through school or won't get a good job after I graduate.  I had to get a student loan this year and I wanted to make it through school by paying for it myself.  I finally came to terms with needing to borrow money.  Now it seems that next year I will have to borrow even more.  I have two years of school left.  I don't think I'll be able to afford big student loan payments after I graduate.  I'm afraid.  I don't want to go through school and not be able to afford health insurance.  I've gone so many years without it and I need medical care.  I am afraid that I won't even be able to afford an apartment after I graduate.  I don't want to end up homeless.  I have a cat that i will take care of.  i am afraid i am developing dementia.  she just crawled on my lap.  lol  cant type easily.  bye for now
