Spn sister Winchester daydreaming help please?

I have been daydreaming about sister Winchester ever since I started the show and read my first fanfic. I did not like the finale of the show and it's been 4 years and I still think I'm not over it, recently on tumblr I made a post about supernatural finale and I received so many different opinions and now I'm just anxious. For some context- I was diagnosed with depression during those 4 years, I have a horrible anxiety disorder and am still dealing with some pretty threatening thoughts towards myself. I KNOW a lot of people daydream about sister Winchester, if someone stopped please tell me how. I'm so anxious since yesterday when I posted that poll on tumblr and I received a lot of attention and now I am just waiting for that poll to be over, it has like a hour and a few minutes left. I think these anxious feelings around the show arose after talking about the finale BUT The maladaptive daydreaming has been going on for soo long. My therapist says it's bad, can anyone please give me realistic advice to if not stop but at least reduce my day dreaming? I wanna cry so much, I'd really appreciate any help Or hell even if you are going through something similar please let me know? Am I alone here?
