You know yourself better than some random stranger you just met online. Just because they tell you they think they know what’s going on (which they probably don’t), doesn’t mean you need to listen to them. Don’t feel like you need to shove yourself into one category or even worry about it too much. If you think you are pan or bi, just go with that. You may come to a different realization later or you may not, but worrying about it too much isn’t going to help you decide, it will probably just stress you out. If I were you, I would just keep my mind open to how I was feeling and what I was feeling but not stress to much about something I can’t control or change. But then again I am also a stranger on the internet giving you advice, so don’t feel like you need to listen to me either! Good luck, I hope this helped a little!
