Negative energy comes also from loneliness itself - so it is a ring of fire somehow.

Everyone deserves some help to deal with their negative energy but from professionals or people who are open to help them with negativity. I think you are not the right person for this as you've said.

Sorry but please don't message me anymore.

I think on the internet it is hard to set strict boundaries because people can reach you in several ways. But how you are doing it is a good and respectful way.

I can understand your doubts about saying these words. You seam like a very caring person and to decline an ask for help is not easy for sure.

But your explaination about the reasons behind your decisions is really good and I can relate to it.

Some years ago I were on rehab for coming over many adictions and there I was in contact with many people with way bigger problems than I had back in the days. So of course I saw myself first as a helper - "they have bigger problems and no one to talk about them"
But this turned into a big task for myself because all of this negetive energy. And so I turned to be closed and not sooo open anymore and finally had the time to take care for myself.
Because in the end we all are human beings with our own problems and tasks.
