Is your question in regards to your own feelings?
I have had a great deal of trouble with this situation myself. I know that walk. It takes me an exceedingly long time to get past feelings of love for another-opposite sex.
If this is the case for you, this may not be what you want to hear but the sure fire spell for this is time.
Time and spending your time enjoying what you enjoy. Whether it be writing, drawing, or even Wicca.
But truth be told there is no spell I know of that will work for this. This is a case of the pathways of the heart. Healing of the heart has a natural ally, which is time.
And rest. And relaxation.
May I suggest some chamomile tea before bedtime, for relaxation? I do not know if you have tried chamomile tea before, not everyone likes it. But, it may help to sooth stress, and help to relax you.
If anyone does have a spell for such a situation do let us know.
The only ally I've found to be of immense help with this is time.
All my best Joanna.
