Need money for Cardiologist

My name is Abigail I’m 25 years of age 
earlier this year I found out I have an Enlarged Heart and high blood pressure and my Heath hasn’t been so good . 

in the past 2 months I’ve been having shortness of breath Tightness in chest and Feeling fatigue. I don’t have medical insurance I’ve been trying to find one to pay out of pocket but
everyone keep saying they starting January 
So now I have to pay out-of-pocket for

everything I do and it’s very expensive I did a
echocardiogram and I had to pay $215 cash
and I did some test and it cost me $135 the same day. 

plus other doctor visits that cost about $450
all this in about 5 weeks and I’m not working 
due to the pandemic
please Anything you can donate I would really appreciate it I just want to get to see a cardiologist because I have to pay upfront and all the visits  are over $400 each time
