Life after college

This has nothing to do about adult relationships but its one of the more active topics and I can really use some comforting words. Im about the graduate college. If i even pass these 6 classes because my mental health is so bad. I was depressed throughout college because I haven’t figured out my life purpose. Im so nervous to finish because I feel like my depression will come back. Its pretty nerve wracking. Im graduating in Business Administration and its so hard to find a job right now. I don’t go our often and only have like 1 true friend and im scared its just gonna get lonelier once I finish. If anyone else has felt this way or has any advice it would be greatly appreciated!
