help my daddy get surgery

Hi, my name is caitlin and about a month ago my daddy had 2 mini strokes and they believe to see 2 aneurisms in his brain that could rupture, he has to go in for an angiogram and the copay alone is 1800$  and were already in debt 3,000$ in medical bills. Because of the strokes my dad is no longer working and it's been left to my mom to pay for everything, we've resulted in cleaning for our landlord to take money off our rent so we don't end up homeless. My mom can not afford the angiogram but he needs it, we need to know what's going on in his brain, my dad is my whole world and I don't know where I'd be without him. Please every and any help is highly appreciated. I mean my sister is helping pay my mom's bills, my boyfriend is buying food for us to eat because one person working in the household isn't working, I apologize for rambling and bouncing around but we just really need the help. I need my dad to get better cause he has so much to live for.
