This is quite normal for your age. It’s like you have one foot out the door but you’re not sure that you want to go. It’s like in some people who realise that they are growing up and they are afraid of what the big wide world may have in store for them. You might even feel that you are growing up too fast. It’s like you can go out but only because you have a safe home to come back too. Rest assured this will pass. Just don’t beat yourself up too much in the process. Just go with how you feel, trust your instincts. And I wouldn’t be surprised if one or two of your friends have felt this too and are also afraid to bring it up thinking it’s strange. You don’t have to tell anyone, just go with the flow it’ll pass.
