Fed up with a close friend, what do I do?

The situation is rather complicated? Birthday gifts or speical occasions I’d often treat the people close to me, such as family & friends, with a token of my appreciation with a present. I’d usually put thought and meaning into each one of them. My considered Best friend which I’ve known for 4–5 years always received something from me and every year she would have given me a single card; years after my birth date had past. The same message was always writen on it, saying that it would make up for the two years…

It’s not that I’m selfish. I do understand the meaning of giving with my own kindness without expecting anything in return, but Im just fed up? Last year my gift to her was an hand drawn picture worth 7 hours of my time which I had also framed. Hers was a belated card.
