How should I feel

MIL hates me for who knows why. She is literally crazy. She  never acknowledged my child when they were born or since even though we are in the same Ward and live less than 5 miles away. Didn't show up on the day my child was blessed. Now she is going out of state to attend the newest member of the family's baby blessing. How should I feel? Trust me I've tried to take the high road and mend this relationship for my child's sake and she refuses.
