Dont be shy or scared. We are only words on a screen right now. And you only have one judge in life. At least thats how I feel. And only you answer to him.
So with all that said Welcome. And Im sorry to hear about your situation with the ex. But life does go on. And now your focus should be about you.
Right now you need to make changes in your life that will help you and they can be small changes just as long as you start to feel better about yourself.
Changes in your daily eating habits is a great start and also getting some more activity in your daily routine is also a great help to. Park farther away take a walk and seek out better more healther recipes to try.
You will make it thru this time and when you look back and see how well you did you will be even more in awe of how trully great you really are.
