What can i do bout my insecurities?

I am 27yrs old a qualified nurse. jus started working on the wards, been in outpatients and theatres previous to this job. I'm struggling cus i have no confidence. I watched the apprentice and seen kate who is stunning (i'm not, pale and redhead, see 360 photo) and intellignet, jus perfect. I am clumsy forgetful... I have a 18mth old daughter and one due in aug. I have no friends or parents(deceased). other members of the family either live in plymouth or Ireland. I hav no fashion sense cus i don't now how all the other girls always look glamourous. I'e recently got engaged, but don't thing it will last cus of my insecurities.I'm plain and boring. I can't copy hairstyles cus my hair is too thick. Never can get make-up that suits me. I can't swim tried for years. Can't drive, tried but a disaster!
