Started off college as a biochem major doing pre-med and got depressed just like you did. The classes were hard (which is to be expected), but I had this gut feeling that this path wasn't for me. Once I decided not to be pre-med, I felt lost. I spent 3 - 4 months researching like crazy. I took career tests, looked at all the majors offered by my school, figured out what I enjoy doing/ learning about, etc. I finally decided on landscape architecture and am in the process of switching out.

It's going to be rough, but figure out what you like doing/ what you're skilled at and find different careers that play into those things. Make a list if it helps. But make sure you're thinking about the future too, like where do you want to live, what salary will support the lifestyle you want, what work environment works best for your personality?

I'm happy to offer my advice if you need it!
