Still living (just),

Do not ever think you must completely get out of the game if that is what you want. It would not do to mention names but I know this guy who admires women to the point he has and is willing to have relationships with a lady up to 30 years younger or older than he. There are many people looking for good relationships and age should not matter as long as they are above the age of consent.   

Accentuate your strong assets whatever those may be. Good looks, intelligence, curves, smarts, humor, whatever. You would be surprised at the possibilities.

You simply must get out of that depression even if it means seeing a professional. I had been the "victor" in all my previous break ups and thought I was invincible, but boy did I get what was coming to me, a through comeuppance! It is not anything I would want anyone else to experience.

Blame yourself if that was true, it was in my case, but no relationship is one-sided, as we all know.

IT will be tough but you will make it if you want to. What are the alternatives? Certainly much worse than attempts at self-help or professional assistance and finally losing that tunnel you speak of.
