Life is too short to feel ugly!
Ignore the "beauty comes from the inside" nonsense - you are allowed to feel what you feel and want to look the best you possibly can. You want to look in the mirror and at photos of you and be happy with what you see.
Confidence and happiness are important! You matter! Your appearance matters.
Get a stylist - personal stylist can even work online. Pick a stylist that works with high street fashion, keep the cost low, but someone recommending the colours and shape that work for you makes all the difference. It really is not expensive, some stylist can do even do an online shop for you with Vinted items!
I can recommend some groups and stylists if you want.
Be active - you will feel better and a toned body always looks better. It's more than important for women as they are getting older.
You can improve your skin, it needs hydration, and using the right makeup will make all the difference. Does any celeb ever goes out make-up free? No. There's a reason for that.
Same with a great hairdresser, they can help - but you can get online consultation with someone who can at least discuss what would work best for you
You are not getting "ugly", you are just changing.
