I don't think you are being a baby, not at all. Having lupus sucks and I hate it too!!! I live in Georgia, so I understand what you mean by this heat, it's been murder. I can't be in the outdoors for more than a few minutes without feeling sick. I do leave the house though to go to the store etc., but not for any fun outdoor activities. There are days when all I feel like doing is screaming and using some unacceptable language,( but I don't.) Refrain, refrain!!!!!
Summer will be over before long and maybe we will be lucky enough to catch a break and enjoy the weather again. Try,(I know it's not easy) but try to stay positive.
And shoot if my husband went out on saturday and came back with goodies I'd jump for joy. lol
Take care and((((( HUGS))))).
