Your challenge is actually not a problem without a purpose but has helped you develop sides of you that would otherwise have remained obscure to you. The trigger for it was indeed your father's suicide on your birthdate, which strongly impacted you without being conscious of it then, but in no way it is the cause of being manic-depressive. The causes are manifold and are not rooted in this current life-stream of yours, yet they influence you strongly due to the nature of certain unfinished business and loss of loved ones (children of yours) in previous lives. The loss drove you crazy and you are now dealing with the grief (which you never did back then). As suggested, you may look up the section on Sacred Santemony on my web site www.ener-chi.com and see if you resonaate with it. You may also benefit from eating very little or not protein foods/products in order to open your capillary walls and permit nutrients to reach the cells of your body.
