Well, Katie, I think you're a normal, healthy young woman who is in tune with herself. The fact that you are willing and able to consider your reactions and feelings tells me that you're on the right keel.
Throughout life we all tend to take critical looks at our actions and reactions and temper them with a touch of experience and common sense. I'm sure you're a-okay and I agree that just touching base with a school counselor might help you recognize some of the touchier matters. Once you can identify specifics, you'll be more confident in controlling them.
Being a sensitive individual is an asset, not a liability!
