my parents only seem to call when they need money

i've been struggling with this for a while because i don't know if i'm being selfish or if my feelings are actually valid. my parents usually only reach out when they need money. i don't mind helping with their maintenance medicine, household bills, or daily expenses because i know those things are important. i've been doing what i can even though i'm renting my own place and trying to make my salary stretch between bills, groceries, transportation, and everything else.

what hurts is that after i send what i can, they almost always tell me it's not enough or that the amount is too small. i don't think they've ever really acknowledged that i'm helping in the first place. it makes me feel like no matter what i send, it'll never be enough.

i'm not rich. i'm just trying to balance taking care of myself while still helping them. lately i've started dreading their calls because i already know what they're going to ask for, and i hate that i've started feeling that way.

i wish they understood that i'm trying my best instead of making me feel guilty for not being able to give more.
