What do you do to stay busy and keep from feeling lonely?

Hello, I’m currently 30 yo with no kids, no friends, no bf, and my family doesn’t really do things. I have tried to make friends and it doesn’t work. I’ve tried soo hard to date and meet someone, but dating is so horrible today. I just don’t know what to do anymore to keep the loneliness away. It’s gotten where I don’t even do any of my hobbies anymore. Anyone going through anything similar? What do you do to stay sane and keep the loneliness away?
