This makes me feel bad

I’m matron of honor in my BFF wedding and I just told her maid of honor (planning the bachelorette) that I can’t go to the bachelorette and I feel like shit about it and am afraid she’ll be so mad or disappointed when I tell her. I just can’t afford to go (plus the weekend before i’m putting out money for my cousin’s wedding + I start school next month that I’m paying for) and I have concerns over covid bc I have 2 toddlers. I’m not an AH for this am I? Bc I feel like I am 😔
