I am a medical student and very high achieving. So my depression leads to thoughts that I won't be able to realize my full potential and that I won't become an amazing doctor. I think my depression may be related to not having a regular routine at the moment. I am on somewhat of a break and my sleep and wake times are very erratic. I have been trying to keep up my exercise too but in the past couple of days it hasn't been possible. I don't think my thoughts necessarily make me depressed, I think it is more biological.
