That's a tough spot. Talk to someone about it - therapist, a mentor, a trusted friend. Especially if any of those people have some knowledge of the things you're doing so their perspective beyond generic "no ciumonk, you're great" support.

The sooner you do the better.

I had to take a break from my studies because as things got worse, I told myself if I just pushed harder I could get through it on my own. That didn't work out.
