How do u know there is a demon inside of u ? Cuz when I am drunk I feel like someone else [Spirituality & Religion]

If you drink your issues away or get so drunk that you either blackout or other things, addictions are usually to cover up the fact you got personal problems. Not saying that to be mean, just usually it is because that's how people deal with the feels and when people don't want to feel anything at all.

Get help and don't blame demons for your behavior.
