Is it normal i despise any kind of encouragement?

So, first thing's first: I absolutely HATE encouragement, positive or not. For example, last week I was hiking and my buddy was like, "C'mon, Mackie! you got this! We're almost there!". It made me want to turn around and punch him in the face. I can beat on myself and push myself on that way, no problem, but when somebody else does it, it makes me feel angry. Is this normal?

*Side note: I have depression, anxiety, ADD, and OCD.
