I know how you feel. I was a near 4.0 and dropped to a 2.7. I changed directions and started attending a local community college. The culture and stress was much less.

I found plenty of accomplished students at the community college to keep me challenged. Joined an Honors Service Society (Alpha Gamma Sigma) and did well. Did some tutoring and work-study/internships. It worked out well.

I never did graduate. Started my own business and made such good money that a degree was no longer a goal. Ended up buying my first house at 21.

Just remember, there are many roads to your destination. The less traveled roads may be more suited to your needs.

My best to you.
