I couldn't even convince the most beautiful person in the world all the last things because good looks do come in handy in many areas of life, love isn't blind, and people will always judge others based on their outside appearance. I think first you need to get help for your self-harming problem. That should be your prime goal, to get healthy again.
Talk to a trusted adult, and they can help you get the care you need. Your hair is interesting. That's the colour I usually do my hair.
I've never been teased for it. It looks good on me. That doesn't mean it'll look good on everyone; why not try a more milder red colour?
Or even a light brown colour with blonde highlights? (Something that will complement your skin tone.) I hate to sound uppity or rude, but brighter colours tend to look more attractive on slimmer people. You are overweight, and that isn't a matter of aesthetics only, that's a matter of health, especially if you carry the weight in your midsection, which is a dangerous thing.
Please don't starve yourself or binge or anything like that; just talk to a doctor to find out what to do, and definitely try to eat healthier foods, and smaller portions. Perhaps pick up a sport-- not only will that help your weight, but your confidence, and people may see you in a new light. I think you could also benefit from having your eyebrows waxed, and a good brow gel may go a long way.
Your complexion is relatively clear, but there are gels and ointments you can use to reduce skin redness, for I see there's a little here and there. In the end, it all comes down to whether you are happy with the way you look, and you seem uncomfortable with it at the least, so a good makeover may do some good. In the end, though, make these changes for you and not for your peers, for after school ends, you'll never see most of them again.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
