I Can't Take This Anymore!?

It's the time of year again when my stupid allergies start to act up or as the doctors love to call it 'Seasonal Allergies'. Just about a half hour ago (or maybe a little bit longer than that) I had offered to help my parents with some yard work, (like picking up sticks and stuff like that) in the back yard. As soon as I touched the stick which had some weeds on it, then touched my arm, the spot on my arm had swelled up and I got a rash and itched very badly. I instantly put the stick down and showed my parents. They were shocked because they know about my severe weed allergy but they didn't know that touching one stick with a strand of one type of weed on it (we call them worms. I think it's oak pollen.) would make me swell up that quickly. And through a long sleeved shirt no less. My mom told me to go inside and take an antihistamine, wash the swollen area off with soap and water, and change clothes. I just decided to take a full blown shower (I needed one anyways) although I did wash the swollen spot off first. And I took some Claratin. It's just so annoying because I always have to be so cautious when walking through grass. (I remember last year when my best friend got married and we were taking bridesmaids pictures out in this field in the middle of nowhere, we were posing for a shot, and there were all these weeds around me, and as soon as I walked in the field and got in the picture my legs swelled up like a balloon and I was so uncomfortable but I tried to be a sport and look as happy as possible for her sake.) I've told my doctor and plenty of RN's about this problem (when they ask if I have any allergies. They always ask) and they're always like 'Oh, seasonal allergies. You can just take a Claritin if it bothers you. But they all don't know how bad it is. Like it's so severe it makes me feel bad that I can't help my parents out with the yard work and I have to sit on my butt while they WORK their butts off and I can't do anything about it. (I mean sure I can do other things to help out, but still, it makes me feel AWFUL inside knowing that I could be helping them out but I can't because of stupid allergies!) Any advice? No stupid answers please.
