Does your family treat you like a bank?

They seem to think I am a bank or a loan service. I'm not against helping if you genuinely need it but most of the time it's not for emergencies. If I say no I'm labeled selfish or a miser. My brother is a prime example wants 2k for poker swears he will pay me back. Told him no and I got told I'm uncaring and selfish. As is I'm the one funding our mothers care home. Selfish huh.....
