Help Maggie Stay Warm for Rehab

Hi my name is Maggie. I'm struggling with alcohol addiction and I plan on going to rehab on Wednesday but it's going to be very, very chilly and I have no warm clothes. I was hoping to embarrassingly ask for a little bit of help getting some warm clothes like a big jacket and maybe a hat. I don't know how much that cost but I just am asking for $50 just in case. If anyone can help me out that would be amazing, but I understand if this is too much to ask
