I had a group of friends from 12 years old to 21 years old. I've only kept in touch with one friend from that time period, and I feel like I can just talk naturally about very mature/deep topics with them. Finding new friends, all conversations feel shallow. But, my one old friend has been sexually frustrated during the pandemic, and is starting to sext me. I feel like this has undermined our old friendship, since I know no relationship is going to come from it. I just feel very lonely, not being able to talk to anyone about the more complicated situations in life. It's either "deep" sexting, or dick pics when trying to find new friends.
