Worried

About my dad. My mom was telling me the other day he has some sort of bump on his back, its getting larger.  My parents have no insurance (just can’t afford it) and so he hasn’t been to the doctor.  He has severely high blood pressure, to the point that if he even mows the lawn it causes him to burst blood vessels in his eyes sometimes. I hate feeling helpless.  I hate not knowing what to do.  I told my mom he should go to the doctor but they wont consider it because they can’t afford to.  I wish things were easier, and I wish I lived closer.  Not that I’d be able to do anything maybe but atleast I’d be close.
