I was just wondering "how" to being more positivity into my life.

I am always meeting

-Drug Addicts

-Perverts

-People with mental problems

-Loners (like myself) with issues, like family issues or they are suicidal. After a few weeks sometimes half a year of me helping them giving them advice, their life improves for the better and they they go about their business and i never hear from them again. In most cases their life improves tremendously and mine takes a turn for the worse, like an exchange has taken place. is this similar to psychic vampirism? If I am leaking somewhere, how can I stop it? Why can't I help myself like this? The way I helped them?

I also meet...

-Con artists e.tc I may go for a job interview, work for them. They steal my stuff and do a runner.

While I do not mind having friends like this it is reaching the stage where, these are the ONLY people I meet. If I leave my house to go out anywhere, sitting on the bus minding my own business, A random person fitting into one of these categories will approach me. All I do is give everyone guidance and support. All of my friends also fit into this category and they never give me any guidance or support back. It's really draining. So I basically asked the universe for a break and meanwhile I am getting it and loving it, I have realised that in order to achieve this. I have had to become a hermit and avoid everyone.

So my questions are

-Why is it only people like this drawn to me?
-Am I too kind/too open with people? Why are they drawn to me?
-How can i stop it and bring more kind open minded people to me?
-Am i suffering from some kind of energy leak?
*I don't think that I am better than anyone or superior to anyone by posting this but, I just want to know, why. *
