This is in response to your reply:
The feelings that I have for this person are not of a sexual nature. I have not given that any thought in the least, which is weird for me. It is just a sense of completion when I am around her: I feel totally relaxed in her presence.
It has been a over 6 weeks since I last saw her and not one day goes by that she is not on my mind, so much so that it affects my work and I spend most of my days being very depressed.
I have discussed this with my wife and she seems to think that it is bordering on obsession and that I may need to talk to a professional about it. Either way, it does not resolve the way I feel about the person.
I try and try to blank her out of my mind but nothing seems to work for long. I do however get to see her in 2 weeks and this scares me because when I leave her presence I usually get very depressed and numb.
