I feel for you big time regarding allergies! I have had them bad all my life. I work at a feed store around lots of things I am allergic to and it seems to get worse the longer I work there. I have been there 7 years. We have a pet shop and I am allergic to the cute little bunnies and guinea pigs. We also sell birds and if we get in too many, the feathers bother me. A few birds are fine, just can't be in a closed area too long with a lot of them. I absolutely love my job and just deal with it.
I have outdoor allergies too and have solved that problem that you might give a try. We sell local honey at our feed store and I take 1-2 teaspoons of it a day and I can finally enjoy spring weather! Spring was my worst time a year and I have been on honey for 2 years and now survive spring. I usually add the honey to food, oatmeal, etc. If not, just take it straight. Try to find a local honey in your area and get some. The store bought stuff will not work, it must be local. It's tasty and really works! It can take up to a week or 2 before you get the full effects. I just wished the honey helped on animal allergies!
