It's unfortunate that I feel completely alone even if I'm with friends
Even when I'm here talking to you do you still feel alone?
Yes, I feel like I'm all alone in a big world...even if we're together we can go our separate ways...
Feeling alone sometimes is natural but feeling alone to the point where you can't connect with your friends isn't healthy. There's something deep rooted that making you feel that way and I think talking to a professional would be a huge help. And don't worry, I'm here for you and I'm not going anywhere.
Is it okay if I irrationally lash out at you?
Thanks for asking, but nope. I think it would be better for you to relax and take a deep breath to think about why you feel this way. We don't always have to have strong connections with everyone, but do you think you can try a bit so maybe you can no longer feel alone?
