Oz, truly sorry to hear you are struggling with negative thoughts and emotions. Everyone's problems are different, but we tend to all travel the same emotional roads when dealing with them so you aren't alone even when it feels that way. I agree with Debi that negative emotions don't only attract negative beings. The most positive experience I ever had was when I was at my lowest emotional point. If the feeling you had at the time was a good feeling then it's likely not a negative entity. They tend to bring you down, keep you down or otherwise make you feel bad about yourself. If the advice you were given was sound, helpful and seems like it would help lift you back up then I wouldn't dismiss it outright.
