Undecided Question

How to stop being lazy with my self and letting my self go?

I am a 17 year old female and people have been telling me i let my self go lately. I am not the typical girlie girl and i want to be. I rarely do things with my hair, i'm too lazy to wake up and apply makeup, i tend to let the hair on my body grow( legs). I want to be more of a lady. I want to learn to manage my own hair and maintain beauty. I am a "OKAY" Looking female. I want to weigh about 120 lbs, and be a girl by keeping my hair done and makeup. How can i go about doing this. Please help me….
Info, i am 5'2 and weigh 140lbs, i have med. lengh hair, and a brown skin tone.
I want to dress girly too. I mainly wear scrubs all day and want to wear cute girly stuff wear can i buy it? I have a job so money is not a real issue
