Have you had any help with this? If not you need to see a doctor or therapist ASAP. I do sympathize because I have a terrible time trying to drag myself into the shower, especially if I'm due to wash my hair. It seems like such an effort. If you don't already have a therapist and medication please look into it. Maybe you could also get a change of school placement. Don't give up on your chance for a happy life!
I have been through anxiety attacks before. Obviously meds can help. In most cases only meds can. This is kinda crazy but I always like to remind myself of the movie What About Bob. It is a comedy but it talks about taking baby steps in order to conquer phobias. If you have not seen it I think you would enjoy it. After getting out of jail my mom developed a fear of being around people and she will stay isolated as much as possible. I have seen alot of people quit school or put off to the last minute that shich should be done today. When you do go out don't have the expectation that it is going to be a bad day or a bad trip. Think about the people that love you and the reason they do. Fall back in love with yourself and stop the negative thoughts a litlle at a time. As long as you make every day a little better than the day before, hold your head high and consider it a win. There is a time to be depressed and a time to be happy. There is a time to be afraid and a time to be confident. It is a normal emotion just like love and compassion. You are just as perfect as anyone else is. Start looking from the inside lookin out rather than from the outside looking in. Hope this helps. You can look at it as funny or inspirational, I don't mind either way it planted a seed watre it if you wish......Have a grat day.
