New to Food Allergies- Need some advice

Hi ladies.  So my 1 year old is allergic to egg and peanut and I feel like I am becoming a crazy person.  I was hoping for some words of wisdom from someone who been dealing with this for awhile.  When he was about 9 months I let him try some peanut butter thinned out in breast milk. He vomitted within minutes.  He seemed fine other wise but we went to the ER where he got the all clear.  I made an appointment for allergy testing.  He was positive for egg (1.98 blood test) and peanut (1.18 blood test).  These numbers seemed so low and I was feeling pretty confident he would pass a baked egg challenge and outgrow the allergy in a few years - power of positive thinking right?  I know he's less likely to outgrow the peanut one but I'm still hopeful.  A few weeks ago we went in for a baked egg challenge. He got through about 1/4 of the muffin before developing hives on his face and belly.  They gave him Zyrtec and when that didn't clear him up used the Epi.   Last night at dinner he developed a few hives around his mouth.  He only had peas, carrots and mandarin oranges so I'm guessing we may have somehow gotten egg on his tray?  The skillet from that morning was still by the sink.... We gave him Zyrtec, hives cleared and he was fine.   

Here's the thing, I'm a nervous wreck.  I was up all night after the egg challenge and all night last night watching him for a biphasic reaction.  He didn't sleep well because I was shining light on his face every 15 minutes or so looking for new hives.  He loves to eat but I'm terrified to feed him much of anything for fear he'll have some sort of reaction.  I worry all day while he's in daycare about what he may come in contact with.  We have an action plan, daycare is well aware of his allergies, everyone has epi's and knows how to use them but none of that gives me much comfort.  In my head, I know a lot of kids have allergies, especially egg, and that not all reactions are going to be life threatening. But I can't help but feel this sense of dread everytime he puts something in his mouth.  Everytime he coughs, makes a funny face, gets the hiccups I panic.  The doctors are great in preparing us for what to do in the event of an emergency but all of that has resulted in me feeling like everything is an emergency, like every reaction he may have is a life or death situation

Can anyone give me any advice on how to cope?  There is a support group in my area, I've reached out but haven't heard back, they may not be very active and I don't think they have in person meeting.
