have you tried to lay down, relax all your muscles, including facial muscles, eyebrows, mouth, tongue, etc.. everything. put a pillow under your neck, so your head will lower down. then focus on relaxing all your muscles, every muscle. then focus on your brain, and try to think to relax the center of your brain, you can do that by thinking that a sphere is coming out of the middle of your brain outwards, more spheres and more... expanding feeling from your brain. imagine an explosion comes from insides of your brain and goes to infinity from there outwards. continuous waves of expansion. at same time imagine you see everything around you, beyond your room. imagine how you see the neighborhood around you. remember to relax your whole body while doing this. its important to have your pillow etc on the neck, or you cant truly relax the mouth muscles. its important to have the tongue relaxed.
now when you have done all that, focus in the middle of your forehead, between your eyes, remember the sensation that you get when you put a pen between your eyes? focus on that feeling. concentrate to that feeling and try to make it stronger, try to make the feeling to reach inside of the center of your brain, and after that focus on the top of your head, channel that feeling there. feel the energy? imagine you throw all negative energy out of yourself from the top of your head, and at same time you take energy into yourself from the middle of your eyes/forehead (the pen feeling). then imagine you recycle that energy so that you take energy into yourself from the middle of eyes, push it out from your top of head, and that energy goes back to your middle of eyes/forehead. repeat that and at the same time still try to feel the weird feeling a pen gives when you move it it between your eyes/forehead and try to make it feel deeper in your middle of the brain.
let me know how it works. it works for me
dont try to think to become happier, just try to think to recycle the energy.
there are more to that, than the top of the head and the middle of the eyes.
