It's ok to be clingy I believe, it shows how you care about them and that's not a problem at all. Although, if you see this as a problem socializing is probably the best option. You can still hold the dear people close to you but also meet new ones. Socializing can be scary but it's also satisfying, I believe everyone is a good person it all depends on how they react towards situation that describes them as imagure or not. So please understand you're not doing something bad
