Hi, firstly don't be sorry, this is exactly the place to go for support. Secondly I've deleted your other eHelp so we don't get confused and I'll paste the previous one you had below for the benefit of other Support Leaders
I'm thirteen,and was recently diagnosed with a generalized anxiety disorder. I can't even leave my room,I'm so anxious. I always worry about getting hurt. I have no social life,and even trying to speak to people makes me extremely nervous. I'm starting a new school this year as well. I don't know how to explain this more in depth. It's hard to describe an anxiety disorder to someone who doesn't have one. I'll explain more if asked,though. Thanks in advance.

I also just wanted to say that this eHelp system isn't built up for conversation so ideally it's best for us if you tell us as much as possible so we can make one reply trying to address multiple issues. But obviously you can also private message any of the other support leaders who have replied to respond to what they said and maybe continue the conversation further. You say you were recently diagnosed, does that mean you spoke to a doctor? If so I really think the best step to do is to speak to them. They'll be best able to give you advice on what to do, suggestions about perhaps speaking to a counsellor/therapist, and a whole host of other options. We, as users on the internet, can only give you limited amounts of information but your doctor knows all about you, if you can explain to them your concerns, worries, what you'd like to improve on or change, then they can help you. I hope this doesn't seem like useless information to you, but I'm saying it because it really is the best thing to do. If you're nervous or anxious about seeing your doctor again (or maybe even booking an appointment - get someone else to do it, a parent, friend, relative, etc) just try to remember that that's what they're there for. Anything you do tell them is in strict confidence so it's not like they'll blab to everyone, no-one will know about you or your situation.
The thing is is that this won't change overnight, you won't wake up one morning feeling better, even if that's what you want. This is, sadly, a slow, but gradual, process and for something like that you need a constant, someone in your life to guide and support you through it, someone you really trust. Even if it's just your doctor or counsellor it's someone that knows you and what you're going through. For someone like you there is no bandaid or words we can say to get you to make friends easier, as from the sounds of it you sound really worried and nervous in general, so telling you to "be open and not afraid to approach others" is probably going to be useless. it's like telling someone to simply "be confident", well that takes work too.
So I really hope this has somewhat helped you to at least understand that this is something that needs professional attention and guidance, and for that you really do need to go back to your doctor. Just so you have someone to speak to properly, face to face, share all your thoughts and get them to help you open up and understand the root of the issue and begin the process to improve it.
Good luck, and all the best
