Music therory

You know I feel like I hear music differently then other people, I did 3 years of choir have had 2 music Phds, 3 singers that I've dated all try and teach me to sing and the same thing happens every time.

Step 1) They talk about a bunch of stuff that I know nothing about, harmony, beat, notes, scale, etc
Step 2) they try and teach me these thing by singing notes at me then having me sing them back
Step 3) the get frustrated when I can't hit the notes they want because I have no idea when I have
Step 4) they get angry tell me I'm not trying and give up

I was thinking the other day that the reason for this is that I must hear music differently than other people. Take Thursday for example when we were learning that song all I could hear was people voices, I didn't register a melody or a harmony or what ever it was we were talking about. When someone tells me to hit a note I can hit it I just need to move up and down the scale till they have told me I've found it, but ask me to hit it again I won't be able to without scaling. Tell me to follow a rhythm and I fake it till it seems right, tell me I'm doing something right and I'll take your word for it. I don't hear music like a normal person.

Anyway I'm going to do what I've always done when forced to sing, I'm going to sing really low and in the back and fake it till I make it. As for actually knowing the song yeh that isn't going to happen.
