Bridal Party Drama

I'm very recently married and took it upon myself to cover all of my bridal party. But now the bride has booked an extremely talented but very expensive makeup. She's not yet put all her cards on the table to advisors that she is expecting to advise us, but it's been dropped in very brief conversations on few occasions. I don't really want to get my makeup done if it's going to cost me 300 quid. Unfortunately, I am unable to take a second job other than working at hospitals as staff due to my placements. It would have been amazing to be a bit more supportive considering my situation. Because I feel like I don't know if I'm going crazy
