Getting a gf won't magically fix you being sad and lonely, that comes from a completely different area. Try to find communities online or IRL you fit in with, communities that have similar interests and encourage self-improvement. Women like men who work to improve themselves, not because they want to get a girlfriend, but because they are motivated to make a better life for themselves.
