Hi ShanetheArtist. I have had some of the symptoms you are having. Anxiety on top of all this is brutal. I agree with the others in that you should maybe start by seeing a medical doctor first, to see if there is a physical cause for some of your troubles. Then you may need to see a pdoc or therapist to get help in managing the anxiety symptoms.
Find a trusted adult you can confide in, maybe a parent, relative, school counselor, etc. You will need their help to obtain treatment and healing. I know if my child was suffering I would do anything in my power to get my child help.
My heart goes out to you. Best wishes.
