Am I overreacting?

Ta
Today is my 21st birthday and my husband forgot and I'm actually pretty upset about it. This birthday specifically, his birthdays, and our anniversary are the only important dates care about. Id say Valentine's Day too but it's not a big deal, I do love Halloween but I don't dress up anymore haha and Christmas just kinda stresses me out with my family and their 'getting presents for everyone is more important than spending time with 30+ family members' attitude.
Plus him being him, we still have to buy everything for camping and he wanted to wait till the last day to buy and borrow everything today. We leave tomorrow, and he gets off late so we have to run around and hope majority of stores are still open and borrow some chairs from his grandparents before they go to bed. I'm disabled and don't drive (working in it) so I can't get this stuff while he's working. So I'm also kinda stressed out.
