err.
I can't ever be happy with my body. It's an obsession.
You shouldn't be happy with anything unless it leads you to true happiness. If it, in anyway, holds you back or side tracks your efforts...and especially makes it impossible, correct it if it is possible...adapt if not.
If you mean the appearance of your body because of something that is basically unchangeable...such as your height...basic underlying bone structure...etc...then you must learn to adapt by increasing the positive aspects of your body that you can change.
If you mean you may not like your body fat ratio...if it is unhealthful...as high amounts are...then that is definitely something you can change.
A woman is at her most beautiful when she exudes health. Women are supposed to have a healthful amount of subcutaneous fat - layered evenly throughout the body...however, not unhealthful amounts. You definitely are NOT supposed to be skinny. Aim for maximum health above all else.
Diet: Eat healthful foods and never eat a good 5-8 hours before bed...fast once a week..starting upon waking.

http://www.sciencedaily.com/releases/2011/04/110403090259.htmExercise: Just once a week Squats or Deadlift...or better yet Trap Bar Deadlift - and low level aerobic activity everyday will keep the largest muscles of the body growing and the daily exercise will continue to burn fat.
The below link just gives you the basic idea of resistance training. You would just need do 1 exercise...but it must be a major body exercise...either the Squat (In a power rack only)or the Deadlift (or Trap bar deadlift - the safest...the one I recommend for you...the one my son does at home...as pictured in the below link). For a woman it is especially important for keeping your bone mass strong...as you will lose bone as you age. You will not gain lots of mass with this ..you will, however, gain some weight in muscle...and lose greater amounts of fat. Get a weight set for home. If it is convenient...you will do it.

The stronger muscles in the body will always need more calories to sustain themselves...combined with a healthful diet and moderate daily exercise (walking is good...make it fun..walk in a nice park or other area where you may enjoy beautiful scenery).
I've seen your videos...you should have nothing to be unhappy about. You have great natural beauty. Many women would love to be in your shoes. Don't obsess about your image...obsess about your health (I know...easy to say you may be thinking...but I do know about obsession...I had many obsessive / compulsive issues when I was younger...I redirected my compulsions and obsessions into physical training early in life). I've done many physical things throughout my life...I've Powerlifted...run long distance (I've also run a Marathon in decent time...42 kilometers in under 3:30 without stopping once - not great...but I did it because I loved running and had set my two goals at that level)...I've won many physical contests in the Army and later in life in other sports. I know exercise and the practical application of it in life.
Beauty should be a reflection of health and beyond that...a reflection of self...through grace. Economical...efficient motion is graceful. Try Tai Chi...it teaches very graceful motion and is very aerobic in nature (from as low a stance as you can - not standing high). This alone will greatly lower your body fat...just 2-3 times a week at this (take a class) would qualify for your aerobic needs. You will find that it will also GREATLY improve your mood besides your grace. Yes, I've taken Tai Chi also. Now that I am retired...I shall be going back to it. I love the way I feel for days afterward...You must try for low and slow motions...many practice their stances way to high...if you aren't sweating profusely in short order...you are standing too high.
With Physical/Mental health through Diet, Exercise (Resistance / Aerobic and Skill training), and appropriate amounts of deep rest...you can not help but be at your most beautiful. From what I have seen...you don't have far to go.
