Figuring things out later on in life is ok, at least you figured it out, but having the ability to figure some things about earlier on in your life, will definitely be something that works out much better. Get your life in order. Sit down and try to write down a list of things that you hate about yourself, then take the time out to write down a list of things that you like/love about yourself. Look at that list really closely for a moment or two and spend the rest of your day just trying to take it all in, so that you can start figuring some things out for yourself sooner rather than later. Cellulite is not a medical condition that is going to kill you, it is not a disease, it is really nothing for you to be overly concerned about.
Yes, if something makes you unhappy you should make every attempt to correct the issue, if there is something that you can do about it. For the things that are completely out of your control, leave it alone, forget about it for awhile, start focusing on the things in your life that you can possibly make some changes to, including your health, both mental and physical and if curing yourself from your cellulite problem brings you enormous happiness, then I suppose you are doing nothing wrong. If it gives you a good feeling and is not harming anyone else along the way, just continue going for it because obviously there is nothing wrong with what you are attempting to do to make changes in your life.
Get the facts straight before determining whether or not something is bad or good, right or wrong, ugly or pretty. Know what you are talking about before you say it or even think it for that matter. If cellulite is preventing you from going places with your friends or family members, then you should start talking to your doctor about coming up with some type of plan that can help you to get rid of your cellulite once and for all. Not everyone wants to tell people about their concerns, especially if they feel that it is over something silly. They do not want to be judged in any way. Do it on your own, you are more than capable. Read up about the facts on cellulite and the different methods that actually do work, so that you can start focusing on making the changes that will bring you happiness.
