how do i be confident with my body?

Just have a BMI between 19-20.9 and don't compare with others.

i can not really help you entirely to change your mind with snap of fingers but what helps is that you focus on 3 things:

1. What are some detriments of your desired properties (and analphabet's example list)

Are you physically healthy (no aches, or pains related to your physical dispositions)?

 For large luscious titalage dose cause pain in back, due to uncomfortably heavy top front of the body. You do not need those,

Hip and tights are not that much of a problem either - they do not get in they way do they? i would assume massive hips would cause some seating problems ... actually i am quite certain that sitting on big but is rather annoying.

Whats a flat stomach good for? what dose that bring you?

2. It is not necessarily what you lack that matters, but how you creatively highlight your actual possessions (salesmanship).

No i dont mean stuff things under your pants or something like that but maybe wear tighter pants to better highlight your curves, push up bra and such, there are centuries of fashion ok? you can go and look up at ways how to do this as presented by professional beauty vloggers (apparently a huge buziness), many of those do it for free.

3. You can have validation from people not just based upon looks but personality.

Why not skype your fashionable friends and talk with them how best achieve point 2? more interaction, more fun and all towards bettering your future self. Just dont go on buying spree of items.

What i suggest here is that almost everyone knows someone who pays excessive amount of attention to their appearance, such people do like to share this and since we are ALL locked indoors you may aswell make their day more interesting by talking with them about such things. (yeah yeah not everyone will reciprocate but it is far more likely they'll be happy they get chance to have SOME distraction from the boredom)

No i don't know what i am talking about and NONE of this will magically fix anything - those are however good first steps to try and make. not an immediate change but at least you should get little bit away from this slippery slope.
