I'm not sure if this will be encouraging to you now, but it is probably better that you stayed in the semester so that you have something to focus on. Personally, I am not working or going to school and I know that being stuck in this rut of no daily routine is definitely NOT helping my depression. If you've got some semblance of a routine, hold onto it. Every day isn't going to be easy, but when you've got something important that you are working on or going to school for, it helps make the overall picture a little better. It gives you that purpose, something to wake up for every day. School can be very overwhelming, but just keep your end goal in mind.
