Do you think i attract supernaturals?

No, all of this is in your imagination.

You have made the mistake of accepting the notion of metaphysical beings and influences, probably as a result of being raised in a home, where their existence was never questioned.

I doubt that you'll ever be cured of your belief in magic. You might as well go ahead living in a fantasy world.

I hope that you also take practical measures to keep yourself safe though.

Although this portion of my answer is shorter, my first and strongest opinion is that this could be psychological - if you're on some level resistant to moving, or unhappy with the situation, the stress could manifest physical symptoms, such as sickness. I think it wouldn't hurt to maybe even discuss this with your physician, and see what their input is.

As far as spirits go, this is tricky. The idea that new spirits in each new place would make you sick seems a little strange to me. Now, I'm not trying to discredit your friend here, however - do you know for certain that they can see? Have they given you information that matches your experiences, but they could not have previously known? Telling someone that they have a spirit attached to / is following them (especially if it isn't human), is a big deal, and can cause a huge amount of stress for the person. Since you name this person as your friend, I assume you trust them. Therefore, get as much information from them as possible. Ask them to describe in detail what they usually see in general (what their abilities are), how they experience knowing it's there, why it's there, etc. Ask them about the particular spirit that they see attached to you, and again, get as much information out of them as they'll give you. Most important of all, does your friend have any insight about how to safely get rid of this thing?

The second thing you could do is find a reputable psychic medium in the area. Find one that specifically can see and commune with spirits. Research them online - read other reviews people have posted about this person's services, what their success rate is, what they charge. Steer clear of someone charging you an obscene amount of money for a small amount of your time - personally, I feel this is unethical, as you're going to them for help. Find someone who charges a reasonable price for their efforts. Ask about the health issue you have each time you move, but DO NOT offer up the idea that it could be spirits until AFTER they have given you their answer - you do not want to influence their response. If this person tells you that it is a real physical problem, make sure you see your doctor before you follow any advice that a psychic may offer. If the psychic gives you information about a spirit, compare it with the information your friend has given you. Make sure to ask how to SAFELY remove the spirit's attachment to you.

Also, as a side note, be careful about wishing to see the dead / spirits. ;) Sometimes it's not as awesome as it seems, and can be frightening, even sad at times. (Personal experience)

Again, I want to stress that I think the cause could truly be psychological, and I would suggest following that route (and possibly ruling it out) before tackling the possibility of a spirit attachment.

I seriously doubt its ghosts and spirits, but try contacting a priest and see what they say.
