Emotional Freedom Therapy or EFT is a no-nonsense way of removing phobias and irrational fears, it works by tapping energy meridians on our body.
Magnus Haveluck of innergametapping.com has put some guided sessions online specifically aimed at improving confidence with women, and they are highly recommended from me after trying them out.
From my personal experience, this is very quick and powerful. I had just one intense session of this and I uprooted a lot of deep rooted blockages I had. I’ve since applied this technique when facing up to all kinds of inner issues. I recommend taking a rest after doing these videos, as I often feel very drained after a session of this.
