Trigger SI

I'm a trainee t, believe it or not. I've SI in the past, and recently, and am really trying to stop.
I have a couple of scars on my arm, I think sometimes people notice them. I'm still a couple of years away from qualifying so I'm hoping they'll be gone by then, but I am working as a trainee with clients.
I always cover up, but just wondering, what would you think if you saw SI type scars on your t? Would you be disappointed? Would you think them less able to help you as they have clearly had issues themselves? Has anyone experienced this with their t?
Thanks
