Empath In Need Of Assistance

I became aware of my "abilities" almost a year ago. It started around the time of my high school graduation. A lot of things happened around that time that really changed me and a lot of things around me. Which makes me wonder if that's what triggered me being an Empath. I noticed before then that I could always know things without being told. Like if something was bothering someone I cared about and was close with. I just found out what I was called was an Empath. I new had some sort of ability, but didn't know what it was called.

But my problem is I some how have a block on my abilities. It began about a week and a half ago. I have a demon (I'm wiccan btw) that's been following me for some time now. I have accepted it and kind of just go about my day. He occasionally makes visits and stirs things up but I normally don't let it bother me. I was having issues with one of my really close friends one night and the demon showed up. I'm not quite sure how to describe what happened but I felt a huge lump in my throat, a knot in my stomach, a pounding headache and a severe urge to cry. And since that night, I have only been able to feel a few things. Unlike normal where I feel things from my loved ones all day, every day. I don't know how to fix what's wrong with me. I don't know if it was the stress from my friend or if it was demon. And now every once in a while my body does something like a cold chill. But its not a cold chill, I know this. Cause its not a cold feeling. I feel like its my body trying to use my abilities, but something is blocking it. I really don't know what to do to fix this. I hope someone has an idea. Thank you to all in advance.
