I'm so mad!!!

Not only is today fathers day, but it's also my baby's first birthday. We planned a bbq birthday party for her and for fathers day at the park, and my dad just now texts me and tells me he can't come because he has to stay home and take care of his weed plants. I'm so angry and disappointed I'm literally crying. Idk why I even make an effort for our relationship. We moved 135 miles to be closer to my family, and still never see my parents because they're too busy growing weed. Am I over reacting, or would you all be upset too?
