Subconscious anxiety

Sorry, this is my first time doing something like this, and to be honest, I still have no idea how it works.

I have a problem with subconscious anxiety. It has started to negatively affect my education, work, and overall life.

When I’m at university and we have to do something with our hands (some kind of experiment), I start shaking. The strange thing is that I volunteer to do it because I don’t feel scared, anxious, or ashamed to perform in front of my professor and colleagues. But when I actually start, in that moment, my hands begin to tremble. I feel nervous because everyone can see it, and in the end, I’m unable to complete the experiment properly.

The problem with hand tremors started a long time ago, but at that stage, it didn’t affect my life significantly. Now, I overthink it all the time. I feel like everyone is staring at me and judging me, thinking I’m incapable of doing this job (I’m in veterinary school, so I NEED steady hands). I should also mention that I experience tremors even when I’m at home, alone.

My laboratory results, including hormones and insulin resistance, are all normal, so it’s clear that the problem in ym head and I’m terrified.

I am aware of my problem and i want to solve it but i don't know how.
