Consult Psychologist. You report symptoms that may be due to an anxiety disorder or depression. Please reach out to a local psychologist who has treated these issues. I recommend CBT psychotherapy to start. Many problems can be helped in a few weeks of therapy. If you need further help, like medications, your psychologist can refer you. Also consider talking with your primary MD for an evaluation and possible meds.
