A lot like fasting, I've noticed that it hurts most for the first few days - afterward you may or may not feel it anymore. Luckily I have friends IRL who I can talk to, parents who care, and starving romantically in my case is a bit more like going diabetic and always having to pass on desert rather than missing the other 3 meals. I think something else you wanna do, if you'd like to remove the pain, is see the quality of what other people have 360 and see if you really want it - most of what we see when we think of relationships off the top is the highlights rather than the basic mundane aspects, the friction during those times, the fights, and when I look at the quality of most people's relationships or realize I'd really have to drop my expectations about a partner's personal ethics on it I realize that although I'd love to find the right person I'm still far better off with no one than I would be with the wrong person. Being that these days relationships in general are far more performance-based and fairweather than they've been in a long time I really don't feel like I'm missing out on as much.
