Been seeing a CBT therapist for a few months now. Gone through all the reasons why, doing modo sheets etc, challenging automatic thoughts etc.

Found it difficult at first, but now not so bad at doing them. I do one and it seems 'OK'.

Unfortuantely, 10 mins later I'm worrying about the same thing again.

Now, it all seems like a good idea this CBT, but I cant help thinking, is this all it is? Or am I doing something wrong? How do I force these alternative postivie thoughts into my head? Should I be contstantly re-reading what I've written?
