Feeling Awful After Gift Exchange with Sister

Yesterday my sister(5 years older than me and is able to work more than me, I'm disabled) told me that she felt I didn't put any effort into her gifts because there small and comparative to what she got me don't cost as much. It made me feel awful(I still do). She is a quantity over quality sort of person which makes the holidays really expensive for me and she knows this and she says "well I still buy a lot of gifts for you and there decently sized). however she is incredibly picky about the gifts she gets and for me I'm okay with it if it has something I like. I'm tempted to just give her money in the future but that would just cause more problems. I have no clue what to do anymore.
