I'm sorry. I feel the same way, tbh. Feeling like you have nothing to offer to others.. and as such, no reason why they should love you. Remember, though, that you've been able to make connections here. Even though it's not the "real world", you were still able to make connections with real people here. If what you said was completely true, that wouldn't have happened.

I'm sure you do have a lot of qualities, but your past experiences and current life situation make it harder for you to see them, or use them to their fullest potential. But they ARE there - please, remember that.
