What really bothers you & how old are you? A complete overhaul on that scale is a massive thing.
What about your appearance is making you unhappy? Start there and work from that. There are many generic 'things' you can do, but they may not be the things for you. You have a massive list there, is it better to pick a thing you do like & work from there? There are beautiful things about us all, a 'fix list' of things we hate is very negative.
So, what do you do well? What do you like about your appearance & personality? Take that & make it shine, polish the best bits up, make them sing, if you can do that people are drawn to you, you become attractive, your faults diminish. Don't gloss over the cracks, embrace them, I have terrible teeth & grey hair, do I let them bother me? NO, I play on my fantastic bone structure, mad hair and green eyes & the confidence shines through, that's what people love.
I could get myself 'fixed' but it wouldn't be me.
Great clothes help, buy the best you can afford, don't look at fashion, look at what suits you & never buy synthetics, buy great shoes - they make you feel fantastic.
Love yourself, cherish yourself, don't mess with yourself, whack a bit of mascara & lipstick on, buy great foundation, stride out, have fun, don't worry.
