In this busy day and age people seem to get caught up in the moment. There is so much on-line communication out there that someone is likely to read a post or comment and have something else on their mind. This results in totally forgetting to respond, or in some cases they might not think it is necessary. Because of your sensitive nature you would always respond to your friends. Sometimes it is hard to realize that others might not be so quick to do this.
You have a good sense for what makes proper communication. The lack of response has nothing to do with you, it is just a result of people being caught up in day to day activities. Like you said, your friends always talk to you when they see you at school. Please just don't worry about this! If it is making you uncomfortable, you might want to limit your on-line communications with these friends who do not respond. Waiting for a response which is slow in being delivered can result in anxiety and frustration. You do not need or deserve this! Just go back to school and enjoy this second semester!
Take care!
