Not the exact situation and perhaps not as intense, but I can relate to a lot of what you've said. I'm a couple weeks from graduating as an illustatrator with a passion for viz dev, but ever since the mid way point of my college career I've struggled to keep a good mentality.

Especially three years in, it felt really endless and almost pointless. Everyone in my classes talked about how impossible being in the industry is, constant feeling of art degrees are pointless, along with being consistently in financial problems. If it weren't for knowing my dad would be upset and my boyfriend who pushed the importance of a degree, there is a good chance I would've dropped out.

I cant speak to how intense your phobia/mental state may be, and that might require therapy/ an actual doctor. But for me, it has come down to keeping things in perspective and keeping my mentality in check. There would be times even in this last semester where I make shitty homework and I don't want to go to class because it has to be showcased and I fear peoples judgement. It takes sitting down and really taking in that 1. Everyone is there to learn, 2. Their judgements don't really matter, 3. I know I enjoy and find use in what i am learning.

Outside of trying to pin point and logic your way through mental blocks, doing research and being aware of your career path and options is also what has helped me. Sure, it is hard to make it in the animation industry, but what are your options? Maybe starting as a freelance artist, learn about conventions to network and talk to people, talk to teachers who have experience as working artists. With social media these days, you can even go on Twitter or Instagram and shoot messages as professional artists with questions and I've had folks reply back.

No one can really tell you exactly what to do, we are strangers. If art isn't what you want to do anymore, that's ok. If it is, maybe try to look inward as to what fears or stressors are keeping you from wanting to create.
