I panic when I try to draw. How do I get rid of it?!?

Let’s start with this. I love drawing. However, recently (in the last couple months) when I try to actually draw or challenge myself I start to feel sick, panicky. Just thinking about it makes me feel like I’m about to go into a panic attack. I hate it so much! I want to draw so badly, but everytime I really try I start to go into a panic! (I’ve had once or twice where I’ve been able to actually draw)
I don’t know why and I don’t know how to stop it! It’s really effecting me like.. I was going to draw right now but I got the anxiety feeling and so I didn’t draw. What am I supposed to do to get rid of this?!
Also, my parents don’t believe I have any sort of anxiety and won’t let me talk to doctors or anything about it. I’m also homeschooled, so I can’t really get to a counsellor that way.. I just am tired of this and don’t know what to do! Please help!
