Help please - i think i have a serious mental illness - ( maybe 2nd post idk what happened to other)?

I am a psych Nurse and can tell you that you don't have a serious mental illness. but you do have a cluster of symptoms that may relate to anxiety, stress.You do need to see a doctor to sort out if these physical symptoms are of physical problems and if so treat them. When that is sorted out a psychologist would be best to help with the self esteem things and perhaps establishing some positive communication with your family and guide you toward self valuing tasks and sort out your surplus fears. Good Luck - you are not crazy
