That is a lot to be dealing with. I'm so sorry you have to have all this going on all at once!

Is there any way you can get to a doctor and get something for anxiety or panic attacks? It sounds like it's an anxiety issue with the chest pains, as they mimic heart attack symptoms (so you don't have to worry about that!).

Hope that things will calm down and get back to normal soon (and that your grandpa will be doing better).
