Oh my gosh... I actually recommend you to talk to a fellow forum member name Len Walker. She might be able to help you out a lot with this. You might have other activities going on than I thought. Yeah I hope you have learned some self-defense techniques. I listed some places where you can start learning some techniques!
Self-Defense Psychic - some good posts here and there for self-defense in psychic terms.
Psychic but Sane and
Len Walker's website - there are a lot of stuff you can learn from these two people. Also research more about elementals on Len's site. Your place may be on the receiving end of these guys.
Grounding Yourself - fantastic ways to keep yourself on earth. You need balance between the physical and the spiritual realm, otherwise, you'd go crazy/tired/etc.
Talking to Guides/Guardian Angels/Higher-Self - pay attention to Midnite's posts. He has some powerful techniques that you can learn to protect yourself and start talking to your guides and GAs!
As always, Erin Pavlina's website contains a lot of information you may find valuable as well.
Love and live light,
Veloci
