Hey Sleepless,
I took the liberty of looking at the pictures you posted on your profile. Hun, you are stunning. There is nothing inherently wrong with make up but feeling dependant on it is not a good thing. My first suggestion would be to maybe try some more natural looking make up techniques. I noticed you have a real 'look' going there with your bright red lipstick and thick black eyeliner. Really there is nothing wrong with that, but I imagine it might be very time consuming. The best make up enhances your natural beauty. Your eyes are beautiful. Have you ever tried wearing a light pink, bronze or purple eye shadow? You also have nice full lips that would look fantastic with just lipgloss. Even just going for either the black eye or the red lip would help tone it down and maybe save you some time. My favorite thing about make up is being able to switch it up. While the thought of going without make up might give you a panic attack, maybe going more natural will help you feel more confident in who you are underneath all that?
Really, no one can give you self confidence. It's something you have to build within YOURSELF. Think about your accomplishments. What you're good at. Where you're at and where you have been. Take even the little things and tell congratulate yourself for them. I also think it's important to have an attitude that says "I can." not "I can't..." Challenge yourself a little and hopefully you can come to trust, value and appreciate her more.
