3.Stop thinking in terms of black and white. Such thinking is a cognitive distortion that needs to be addressed. Thinking in all-or-none terms like "I am lonely now, so I will always be lonely" or "I don't have anyone who cares about me" will only hinder your progress by making you feel more miserable.
Challenge these thoughts when they come to mind. For instance, you can probably think of a few times when you did not feel so lonely. You made a connection with someone, if only for a minute, and you felt understood. Acknowledge and accept that statements derived from black and white thinking just aren't complex enough to reflect the truth of our rich emotional lives.
