In a bit of a pickle,any help would be greatly appreciated.

OK,i will try to keep this brief,like really brief, because if i need to say it all,i need to write a book.

A few years ago,i was attacked (more like nuked) by a very evil being. Evil beyond all words and powerful beyond all words. That being did something to me akin to trapping my soul or the vast majority of it into its own dimension. A bit like a twisted version of AP That hurts. A LOT! I could describe it in a lot of detail,but that would just make me sound insane (wich i guess i might be),so i will just say it feels like the most awful feeling of madness and absurdity,together with the most awful melancholy,all that along with something else i can't quite describe.

I have seen the entity,along with its domain in many dreams. It shows itself as either a giant serpent or serpents,a dragon (the one time i saw it as a dragon,someone in the dream said or i somehow knew it was 40 meters long and someone called it The Crystal Dragon) or quite often as a bear of some sort. A few times it was a Polar Bear,but covered in algae,almost like it crawled out of a swamp. Its dimension looks either like a copy of my town,but feeling completely different and the worst feeling possible or like a weird cave with weird skeletons inside of it or if not that,a forest. I have never had any encounters with it outside of dreams. In fact,even in dreams,it never said a word. Those "animals" are more of its simbol rather than the full thing. No paranormal happenings either. Even less than before it came.

I have tried everything to get rid of it or at least to do something to it. Believe me,i haave tried quite a lot and nothing happens. It just seems immune to anything i or anybody else tries.

So i am kinda screwed,both in this world and the next and i will most likely be killing myself in the next few weeks.

I'm asking you about advice of any kind. Can you help me get rid of it in this life? How screwed am i in the Other World when i kill myself if it's actually holding my soul hostage? How screwed am i just for killing myself? Any advice is appreciated!

P.S. i am aware of the possibility of it being some kind of mental illness,but if it's that, it's probably schizophrenia,so it's still worse than death. Also,i'm sure there will be a lot of the boring "don't do it" or "find professional help" etc. they don't help,but what can i do? Still if there is genuine advice,i would greatly appreciate it.
