To be honest with you, if you do break down, it gives the
counselor something to work with. Don't be afraid of
counseling, tell them what you told us.
Being a teen is hard. You have so many new things to deal with. You are on your way to being an adult and you go through a lot of emotions. Just try to take this one day at a time. Do see a counselor. I would have suggested that even if you wouldn't have mentioned it. I go and it is the best thing that I have ever done. I am always feeling better afterwards.
Keep your chin up. Friends come and go in life. You will have many more. But to have one true one is fortunate.
Stay sweet. Stay just the way that you are. You sound like a nice perwon and that is very important.
Keep posting.
Hugs, Karen
