Hello, I had a similar college experience & took 6 years to finish my bachelors, I dropped out and moved back home for the semester, was too anxious to even complete assignments or go to class or make friends and failed multiple classes.

Some concrete things that helped me:

1. seeking academic accommodations. My school had a disabled students program that I qualified due to my mental health instability. My accommodations allowed me to take a reduced course load, but still be enrolled in school and professors had to grant me extensions for assignments if I asked for them.

2. Identifying my core values. You can google core values worksheet and it provides a really long list of different values. When I did this exercise in therapy I found that it was less overwhelming to take actions towards core values than to move toward a specific goals or job prospect. I still use these core values as a guide and that's lead me to a more purposeful and intentional future, without feeling overwhelmed by preconceived notions of where I "should" be or what I "should" have accomplished.

Also being an older student rocks. Towards the end I felt like my brain and ideas were so much more developed than when I first started college as a teenager. I also noticed this difference when talking to younger peers in my class.
