Medical expenses for family

I am trying to raise money for my kids medical expenses due to her autonomic dysfunction. We have had to travel out of town for her cardiologist for testing and while here we found out we have to stay longer for testing. We really need help as we are stuck and have to have this done to help her. There are days she can’t hold up her head and many days she is in bad pain, not to mention the chest pain, palpitations, vision loss, periods of gasping for air, blood pooling in her feet, not being able to stand long at all, dizziness etc. Please help, she had to drop out of musical theatre, youth group, leave her school to be homeschooled. Please please help. Thanks
