Hello cool4kenaz,
First, why do you think the gods are always nice?
Second, I would say that you and your friend had an unpleasant encounter, not bullying.
Now, Loki is my patron. He is a very loving god and very protective, too. I had met Sigyn, and she was very nice to me.
Loki is not a god to be ignored. The fact that you were told to contact him means this is something you need to do on your own, not through your friend.
Some folk misunderstand his aspects and what he has to offer. He had helped me with some issues... and still does... often without my volition.
If there is anything else you want to know, just ask me directly.
