I need advice

So my mom says she is very sick and on critical state. The problem is my mom has faked so many things in the past that I don’t know if I should believe her. She looks bad but it could be all the smoking and bad habits getting to her since she is 50. She says she needs to go down state tomorrow for a blood transfusion that he doctor says she so bad and turning yellow, she also says she only has half the blood she needs in her body to live. This has been going on for a month now that she said she hasn’t had enough blood in her body. I’m not sure what to think or do. Do I believe her again like last time and she gets better after a few days after she gets all the attention she wants. Or do I just watch and wait. I don’t want to regret anything if she actually is sick but she is always known to make up things or make things bigger than they are. Also what doesn’t add up to me, is she goes to the er in our town, and they discharge her after 2hours saying they can’t help her. but if they can’t help her, I think they would transfer her to a bigger hospital that could and not discharge her..

sorry I don’t know where to post this
