To be perfectly honest, if the first thing I knew about a therapist were seeing the scars and just that, no, as shallow as that sounds I probably would not see them for therapy. However, I strongly believe that someone who's had issues can do great work as a therapist, and if I were seeing someone for therapy and found that out, I would probably just be concerned, but I wouldn't leave because of it. For me, the most important is for a therapist to make room for me and my experiences, just be there for me, and as long as that's working and they're a good therapist and helping me, I would rather feel empathic toward them and not judge. Besides, I'm a therapist myself and, even though I don't SI, I have my own issues and I've yet to meet someone who doesn't, therapists included. So I think it's unrealistic to expect a sort of flawless, problemless therapist.

I wish you best of luck with your training! Take care of yourself and I think you'll make a really good therapist. In my opinion, the very fact that you're asking this question shows that you care about your work and that you put a lot of thought into how clients may perceive you. You really can't change what happened, just how you use it for your own and your clients'benefit, how sensitive you can be to their issues etc. Perhaps talking about this with a supervisor and colleagues whom you trust would help too.
