Granddaughter in Need After Loss

As a 22 yr old who just their grandma I’m not sure what to say in these sort of situations… but as a just a girl my heart is broken. My grandma passed away unexpectedly and I can’t afford all the funeral arrangements all by myself. I hate to ask strangers for help. I feel as though I have no where else to turn. Please help if you can but do not feel obligated. Thank you!
