top two problem

This was one of my very first hands on this table.
I have a hard time playing hands like these. After his last raise I knew I was probably beat but I was so commited. How should play these? I feel it's weak to fold to his initial donkraise altho a minraise usually screams strength. I don't like just calling either because he might be on a heart draw? I know I screwed this up bigtime but any help on how to play these appreciated.
