Mother’s Day is sad day for me

My mom usually goes out with my stepdad for Mother’s Day (they have kids together) so I usually go to church alone. It makes me feel sad. Bcuz even though I don’t have kids of my own, I do have. Godkids and a dog whom I take care of very well.. so I usually just wait till she gets home to give her her gift or if she comes home late I usually have to wait till the next day.
