I feel like a failure :'(?

If you are going to succeed as a counsellor you have got to take the risk and start talking. The problem is smart people tend to be quiet because their brain in busy analysing everything before taking any action. If you don't open up you will get stuck doing research instead of counseling which would be a shame because most clinical psychologists can't even draw up a treatment plan. The patient just comes in, complains about their life and this goes on session after session. Don't be afraid of saying the wrong thing. Speak up and ascent yourself! You will be a good counsellor because of your strong analytical skills!
