Does someone tell you that you must get used to being alone?
I always believe that it is okay to live in the way that others told you, and it is also okay to do anything you want as long as you don’t hurt other people.
So, it is unnecessary of you to get over this. You definitely can live in this kind of way.
If you wonder why you always need someone around to talk to, I think it might be that you have a strong desire to talk. If you really want overcome this, I’d recommend you write down what you want to speak.
