Is there a difference between
happiness and inner peace?
Happiness depends on conditions
being perceived as positive;
inner peace does not.
When you do something you really enjoy, with people you really enjoy, it makes you happy.
This is what you are trying to achieve in this life, to find happiness and inner peace. You want to just be happy, within yourself, no matter what is happening around you. To remain calm and in control, because you know that you are okay. In order to feel this way you need to eliminate fear from your life, once and for all. How do you do that? How do you learn to trust yourself, trust that you will okay, no matter what?
The way to do this is to live in the present, realize that this is all there is. Don't spend your life going over all your past hurts, or worrying about the future. You have no control over either. The past has already happened, you cannot change it. The future is a crapshoot, there are no guarantees.
So take today for what it is, ACCEPT whatever may be happening. Don't try to twist and turn it into what you want it to be. This is your life, at this moment, this is what is happening, don't expand on it, just let it be. Savour the wonderful moments of your life, all of this will help you to attain inner peace.
Remember, it's a process, nothing will happen overnight, but this is your true disposition - peace and happiness; they are in your DNA, your birthright, therefore, you will always be able to learn to trust yourself and find peace within.
