I have sharp pains in my stomach, muscle twitches, cold chills, shaking, neck and back tention, and have bad hypercondria and anxiety.

That is a long list . Of symptoms. I am wondering what part your hyperchondriasis ; anxiety play in this. Are these issues being addressed? It is important to first rule out medical problems. Next would encourage you to look into cognitive behavioral therapy. When your emotional issues are addressed, some of the vague physical symptoms may start improving.
