Anxiety ruining my career, I'm really freaked

So, my anxiety has been completely derailing my life lately, it's started with severe HOCD symptoms but has gone into a more generalized fashion.

This is really bad because I am an artist and I make a living that way, I'm currently a low level concept artist for a small company in my town but I have plans and hopes to get into bigger companies in different cities and the anxiety makes it difficult for me to work or progress myself to these goals, and when I don't work or get stuff done my anxiety gets worse, and I start to panic and question everything.

Lately its like there is the veil or sheet over my brain it clouds and muddies my thoughts up so I can't think beyond basic thoughts and actions. Art is very mentally taxing, it requires a lot of analyzing and thinking. I used to get excited about projects now I see them as exhausting, it's hard for me to muster up the energy or thinking power to figure out what I want to order for lunch much less figure out mathematically correct perspective.

Even worse when I try and work through I get this paralyzing feeling, then an explosion goes off in brand and all these little lightning bolts go through mind and over whelm it.
"this doesn't look good, it should look like this, it shouldn't take so long so and so can do it better, you shouldn't even be drawing this it won't improve your abilities, why even try it won't be good enough anyway" it goes on and on and I try to address all these problems but of course that isn't possible so I end up spending hours on something and achieving nothing.

I've tried all sorts of coping mechanisms, CBT practices, doing small studies, I went back on medication. Nothing seems to work and I just keep getting more worried and anxious with each passing day.

I'm worried if this continues I'll never achieve my dreams, or worse lose my job. It keeps me up at night and I can't sleep. I feel like my mind is in a turbulent storm and I need it to calm down and give me some peace or I'm going to go insane!

I would love some advice or help or a good drink recipe.
