Hello ......
I think at least a little separation between you and your friends and/or family is a good idea. I had similar situations as yours regarding college long ago with next to no support from family with what i wanted to do. It sucks!
I can understand the stress - as you stated, but what medical conditions are you going thru? That was left wide open!!! If there really are medical conditions, would they not keep you from going into the service. I had a duodenyl ulcer when i was 21 - and the Air Force Reserve would NOT take me.
And face it .......... sometimes we're not ready for something as challenging as the work needed for a 4-year degree. I was there, dropped out of college twice, changed my major twice. Then after getting married, with a different outlook on responsibilities, I went back to college in the evening while working full-time days - to finish my B.A. degree 12-years after I had started college at 17.
Things just don't always work out the way we want or hope!
So .......... you don't have to give up the hope for a business degree. It may have to be postponed - but get the stress and medical conditions taken care of first.
An analogy ........ picture a bird flying with a broken wing! You gotta get the wing fixed first - then it's a lot easier to fly!
