Unicorn, it actually sounds like you are working through these experiences in a pretty constructive way - kudos for having the courage to develop and evolve your methods even when people have thought you were 'crazy.' That's just the way it's going to be sometimes. Pioneers and explorers, especially of consciousness are always going to be seen as being a bit kooky.
Regarding sucking in people's energy and emotions from my outside perspective( and I don't really know the depth of your experience) I'd suggest deep mindfulness meditation to help you 'let go' of the energies that you take on.
There are a few interesting modalities and technologies that have sprung up on the planet in the last few years which in my experience are very good for fortifying and increasing the body's connection to the Higher Self at a very deep level. These may also be something to look into. In my opinion the deeper or more cellularly that the body is connected to the Higher Self the easier it can move and flow through experiences.
I've met others who haven't responded so well to EFT and NLP as well, while proficiency of application is sometimes a cause I also believe that sometimes the technique doesn't go deep enough and if a person is sensitive to energies/consciousness such as you seem to be then you'll be well aware of this fact and so the deep change will not occur. Experienced practitioners will see this and work with it, but even so, sometimes what is required is work that it can only be done by yourself - which it sounds like you've done a lot of.
