There are so many psychologists/therapists/psychiatrists/counselors with their own issues and disorders. One might wonder how. But just look at yourself. Isn’t it so easy to give others advice and tell other people what to do and see the right answer, but then when it comes to dealing with your own problems, you second guess, make excuses, feel lost and confused? It’s easy to say. It’s hard to do.
There really is nothing wrong with that, giving advice when you can’t follow it yourself, because people in the end just hear what they want to hear, and you might just be the voice of reason they are willing to listen to. Give your two cents and lend a helping hand because someone might come along and be that one for you.
