Hi Careasa,
I understand where you’re coming from but just want to encourage you to hang in there. You’re learning so much about yourself right now so just be patient. It can be hard to defend why you feel the way you do, especially when your friends are confused by your mood, but there isn’t anything wrong with taking some quiet time for yourself. I really liked the suggestion that Louise made – if you don’t want to do what your friends are doing then suggest something that is more suitable to you. Sometimes just taking a walk, getting a bite to eat or watching a movie with people is enough to keep you connected to your friends.
If there is someone in your group that you feel you can talk to it might not hurt to share your feelings with them. I know you don’t want them to stop asking you to join them when they get together, or for them to feel like you’re rejecting their company, so if they know that everything’s okay and you’re just taking a rain-check for the evening then things should be fine. Just don’t close off completely even if it seems like the easiest thing to do.
Wishing you the best as your classes start – take good care of yourself and remember that you’re not alone ;-)
