i dont know what to do at this point

first post, sorry about anything. anyways, im scared for my future, i have social anxiety so its hard for me to do anything with people let alone talk to them. my parents belittle me on everything. getting a job, getting a car, getting my permit. and i have no motivation whatsoever to do any of this. there is literally nothing that i have as motivation. friends dont seem to help, relationships are a no, and ive already turned to drugs and the such and those dont help except for the moment. i dont know what to do at this point. sorry for the wall. thanks for reading.
