Replying to School dilema.

yea yea yea school sucks, but as of lately i just really dont want to deal with it anymore.  im not happy being in school so why should i keep putting myself through this.  i cant graduate in 4 years because i got into my major (environmental studies) late so i need a bunch more classes than i will have time for in 4 years. my parents are helping me pay for a lot of it but i still have fairly large student loans which are going to fuck me if i finish school or not. just not sure what to do.  maybe take a semester off and get my shit in order and come back later.  any input?
