Pure panic! i get married in 17 days!!

Firstly, I would like to offer some hugs. I don't know if you're a hug person, but you sound like you could do with one.
Second: Why do you feel the hair and makeup was such a disaster? Was there anything particular that you didn't like, maybe something you could try doing differently? Or would you be able to practice a bit more until you feel more confident with what you're doing? Your groom is marrying you because he loves you as you are. He loves you for being you, so ignore the external nonsense and pressure. You are beautiful just as you are, and you don't need to change yourself for one day. I have self-esteem issues too, so I can relate to what you're saying. But you are worthy, and you are loved. Good luck - you're amazing and can do this!

We put way too much pressure on ourselves. Men just have a shower, some shave then they put a suit on and that's it. Done.
I did my own make up, pretty much what I do when I go out. I went to the local hairdressers for my hair. Nothing too ott.
Looking at the pics my friends friends family too (still waiting for the pro ones) all I see is me smiling all the time and being so happy. You will look awesome on the big day, your love will shine through and you are beautiful!!!

I agree, way too much pressure is put on brides. I can guarantee there are very few grooms stressing about their hair not being good enough!

Your fiance chose to marry you because he loves you the way you are. You don't need to lose weight, have a different hairstyle or makeup on your wedding day. You just need to be you.

Hopefully, you have a long and happy marriage ahead of you. And when you are looking back at your wedding photos in 30 years time, you're not going to be thinking 'oh, my hair should have been better'. You'll just be thinking how happy you look.
