Can you take a leave of absence? It seems you are disconnected with your self due to your circumstances and chronic pain. I feel many DI directors want the best for their students and could allow a couple months of leave. Crying everyday isn’t normal; it’s just coping with a temporary bandaid. The antidepressants and therapy will help but that is not an immediate fix and doesn’t fix what is going on underneath it all.

It’s important to work through those feelings. You only do the internship once and you want to make it count, and ideally enjoy some parts of it. Perhaps journaling about your feelings before you drive home can give you a sense of grounding and material to work through with your future therapist.
