Ending something doesn't necessarily have to be a drama. You can decide to do it because it is no longer what you want, you don't need where you are going or you are simply tired of trying to make it work. Your needs have changed or perhaps you can no longer accept what has always happened to you. Don't wait for something serious to happen before letting go of what hurts you. Step away with grace. Sometimes finding peace within yourself is the most important thing.
Often in a path of personal growth the most difficult obstacle to overcome is the difficulty in leaving behind habits or ways of looking at reality, even when we see very well that so far they have limited us. We also become attached to what is toxic, we fraternize with our own anxieties. But when there is no way to find peace and take care of one's needs in a healthy way, then one must find in oneself the ability to rely on the trust that the first step is needed, if not to go towards an already clear goal, at least to get away from a certain unhappiness.
