Doc, im getting a lot of suicidal thoughts, losing my train of thought, i have no idea what i should do, i feel like sleeping without waking up ?

See a psychiatrist: ASAP, your symptoms require immediate attention, start with your primary doctor, or go to urgent care,

Please go to the nearest Emergency Room if your thoughts become plans. If you have not been seeking professional help then first have a physical exam to know if you have an illness that could cause these symptoms. If not please see a Clinical Psychologist with expertise in multiple types of psychotherapy for help and possibly a Psychiatrist for medication.
