also looks should not be a hindrance to going out in the world confidently. If it will help, if you get a nice outfit , or shoes, or perfume, or a hairstyle you like (can ask a family member for help with this) , you might not feel so self conscious
You will know that whatever you COULD control, you did. That is very positive. It is uplifting to have a nice pair of shoes or a nice shirt.
If u are pleased with the effort you made, and whatever nice item you are using that you personally like, then everyone (worth knowing) will be pleased too.
