Everyone has some sort of abnormality, for some it's physical, others mental but there's always some abnormality. Doctors are no exception, they're people also and they have their flaws or abnormalities.

If you have some sort of mental one, then that can be a plus for you because it gives you insight that a textbook cannot always teach. If you're discussing a topic that pertains to you, then you can reflect on it and give information that you have first-hand experience with.

If you want, then tell your therapist, doctor or whoever it is about your plans. I'm sure they will also give you some motivation and as university or college can be stressful, they can understand an increase in stress and help you deal with it better.

It's better as a doctor or therapist to have some experience of your own with a disorder(s) that way you can understand the patient beyond simply looking at what the textbook or therapist manual says.

You can also use it as motivation to better help yourself and others.
