All you have said above sis are true. But now a days, its very hard to find someone you can consider a true friend. Honestly, I am a friendly person but I am not easily get attach to someone anymore. I think, I am just being cautious now especially that I was betrayed before.
You have your reason not to trust anybody. And you're right, it's hard to find true and sincere friends nowadays. But I'm sure someone is searching too, maybe you'll find that person soon.
Hopefully. But for now, I am just enjoying being with myself and few people around.
