sorry Anika, doesn't sound good

could it be melancholy boredom, depressed mood coming on? sometimes i don't feel the depression come on. and then i'm in it. doesn't mean i get stuck in it, sometimes can pull myself out fairly quick. working with the kundalini helps. i do get the paranoia sometimes that someone is sucking energy from me. and remember, that could be purposely by someone, but more likely imho you could be freely giving too much of your energy, and get drained. giving is wonderful and beautiful, but sometimes we're drained and don't know why. maybe run some kundalini energy up your spine out of head and down around to fill your aura, layer with a royal blue for protection. this will transmute any negative psychic energy or influences. i do the same sort of quick meditation around my whole house and property.
