What if you tried acceptance of the loneliness? Meaning, accepting it, coping with it and getting through it rather than trying to resolve it by means that are not working for you, ie, online dating? This would mean coping with the moments of loneliness.... acknowledging those moments as they occur, saying to yourself, oK, I'm lonely tonight, so now what? Then finding your way through it, doing whatever until the morning? Loneliness is often far better than dealing with weeding through all the frogs that one must weed through online to find a good one that may be worthy of your time, heart and trust.
