I feel the same. In middle school I had a lot of close friends so that wasn't a problem for me but I drifted from them since they all went to the same school while I chose a different one. I haven't been close close to anyone to the point where I'm completely comfortable telling them everything. Even if they say they're willing to listen I just feel like they don't really want to. I have quite a few friends now but me (or anyone in the group) being upset seems to make them uncomfortable since they're so playful all the time.
But yeah you can always talk to me if you want. We don't really talk but still.
