Let me apply the famous phrase a lot of us use.
This is more true than you make think it is, and it definitely applies to your situation. You truly only need one friend; one friend that will pick you up when you're down, will lend you a shoulder to cry on, and will open their arms to embrace you. Would you rather have that one, true and kind friend, or would you rather have 1000 "friends" who don't even know you exist. If you fell, or if you cried, they wouldn't even bother to help you up. To be brutally honest, they'd most likely kick you when you're already down. So is it okay to have less friends? Yes. Is it okay to have lots of friends? Yes. Just be sure you know who's truly your friend, and not just an "acquaintance".
P.S. I would love to be your friend! Feel free to talk to me whenever you please! ^^
