Is it normal that money is more important than love

Tomorrow is my nephews birthday. I sent him $20 for 4th birthday. I think I sent him money on his 2nd birthday also. So my sister calls me after she receives the money and gives it to him and says to me welcome to the family over the phone.l felt so offended. I always wondered why I was so distant with her growing up and now I remember why. Whenever she ever wanted to talk to me out of the blue it was always about finding a better job so she wouldn’t have to look out for her younger brother with schizophrenia. Now I remember why I hate money. I didn’t always remember to send money because I was on such strong anti psychotic meds to help me deal with my mental illness. Is it normal that I think my family cares more about money than me?
