You didn't say by a professional, or self hypnosis, but both will work.

I did, and would suggest that you go with self hypnosis for the obvious reasons. You always have it with you, and you don't have to pay anybody. You can also use it for other issues besides emotional, like for health, pain, etc.

It's easy to learn, but takes a commitment of time, and perseverance. I used it for many years until learning about EFT here on the CZ forum. Then I found a shorter version on Youtube.

There are many videos. This is the one i like. It will do the same thing as hypnosis, only faster. It does take the same commitment, and perseverance. Check it out.  https://www.youtube.com/watch?v=PBNoefm5_i4
