Feeling lost and alone - looking for advice

I'm John, 28 years old, and feeling really lost in life right now. I recently injured my knee while exercising, which was my main outlet besides some unhealthy addictions I've been trying to avoid. I started a glass installation business that's had some success, but even that isn't bringing me joy. I'm living with my parents, have no close friends, and haven't been in a relationship in years. I've tried going back to church but haven't connected with anyone there. I long for love and companionship but don't feel worthy. My injury has left me with too much idle time and I'm not sure what direction to take. I've considered looking for remote work but don't know where to start. Any advice or words of encouragement would be greatly appreciated. Thanks for listening.
