My family and other people are really cruel with me… can Satans and Demons help me?
First of all, welcome here as you sound like an external person willing to know more about Satan.
Second but first, I am sorry about how you are being treated. It sound inhuman and unjust.
I know what it means, being mistreated and abused, it's something getting really deep in your emotions. I just, feel this is sad for you. Sorry, man/lady.
Yes, the Demons help the whole of humanity (except the jews, who are not human) every day so - yes - you may be helped if you get in touch with Satanic knowledge.
There is no "magic tool" to free you of your suffering in a second. How I wish this may happen... too.
Often, it's a long process like a slow healing. But is possible and rewarding. I will be honest, sometimes it's hard and though but... you can free yourself from cruelty and internal wounds you may have.
I say this, because often the reason of being severely abused or treated with cruelty, lies in your karma or past lives, and is the result of bad energies stored in your soul (or around your soul, hunting you like a curse). So it's like having a virus, causing those issues. If you break free of your family, the pattern may repeat if you don't heal the root cause in the while.
Plus, the abusing family members are negative people who will hurt anyone else, not specifically you, but the problem is your karma attracted them to you in this life. Or maybe they come from previous lives where they again were cruel with you. Yes the Demons know all of this very well, and taught that to me.
The best thing you can do for yourself now is : stop thinking messy, slow down emotional turmoil, silence for a second your inside crying, and think : "I just do NOT deserve being treated with cruelty, this is NOT my fault. I am NOT doomed to be mistreated for my nature - NO this is the nature of bad people around me, the cause of my suffering. They are responsible, not me!"
Putting this idea (that is, indeed, true) in your mind will help to better situation as people will perceive a barrier between you and them, and will be less cruel. Just a step ahead.
This is standard knowledge but, in Satanism, there is much more like binding your offenders, healing emotional wounds in you quicker than the average John, preventing those problems to manifest again in your next life.
I am not a newbie nor I am young anymore, I have life-long experience of what I relate here, not just theories from books (that I extensively read).
As a living example of healing (that, for me, is still happening with success) I can witness that, yes, Satan and the Demons will be able to help. And they do this with care, kindness and respect, expecting the same in return from you. Just this.
So, don't feel doomed. Don't waste any more time into wondering IF there is help. You already reached help with your post here.
Feel free to contact me, or post on here anonymously, should you wish to vent out your suffering. Being listened and understood is very precious for any suffering human being.
Take care.
