Sorry to hear you're alone right now. I know it sucks.
However, there are things you can do, both for getting that special someone and for your health in general.
Volunteer your time, maybe at a church or homeless shelter. Get a part-time job at a school, camp or daycare, there are lots of girls there who are dying for attention. Befriend a family and get to know their cute daughters. Bring them gifts and treat them extra special. Date a women who already has a little girl, many of them are desperate for a man in their kids life, and you can fill that need they have for a father. Put yourself in situations that allow you to see lolis. I find even a short interaction can be just the spark I need to break the fog.
Additionally, you can do other things just to help your mental health, which lord knows is important given how we're treated. Exercise. Eat healthy. Drink more water. Learn a new hobby, it will help you focus your mind on something other than being alone. Remember the good times. Focus on what makes YOU happy, not just jacking it to pics of lgs. If being around your family makes you happy, be with them. If they don't make you happy or stress you out, then don't. Do what you have to to preserve your own joy.
Sorry if it sounds like I'm preaching to you, but it's the little things that can make the difference ;) I hope you find the girl who puts that sparkle in your pants!
