I honestly do not know what to do anymore. I have social anxiety really bad, to the point where sometimes I don't even want to leave my own house. I'm only 14 and my mom thinks that all my worries are due to hormones and being a teenager and that it will "get better" and everything will work out if I just do it. I dont know how to explain to her why I start to cry and shake uncontrollably whenever she asks me to go into a store with her and why I cant even stand up to go throw away my trash at lunch. I feel like a burden to my friends and family because I know it's frustrating whenever they have to take me out in public or when they wonder why I cant do anything or when they blame themselves for not being able to help. I dont know what to do and my mom wont even take me to see a psychiatrist to prove that I dont just want attention. I really need someone to give me some advice please.
