Everyone else has given you very good advice, so here is a little more...

Since you do not have health insurance you can try Clariten. This is a non-drowsy (for most people) antihistamine that is available over the counter in any pharmacy. They should be able to give you a Ventolin inhaler. This will help your breathing and is available in a generic form, so it is not as expensive. (Not to start a fight here), but since you live in NY state you might want to consider ordering your drugs from Canada.

I am not sure if you can do this, but if you have rugs can they be replaced with hard wood or tile (that will help alot).

Maybe some of the problem is that it is now spring time and all the pollen is starting to come out again. (I know I am just starting to suffer from it again...)

Good luck and I hope that things work out for you and Meko
