I believe that it is depression and and or anxiety I would see a Thearopist right away and talk with them about your problem it's a family intervention specialist so give them a call and make An appt. for ASAP.. Or before you do that try to drink some hot tea and take an hour walk everyday for a week to see if that'll help. If not call family intervention specialist
We can't give you a diagnosis here but I agree with above poster. It does sound like depression anxiety. Are you going through a stressful time right now? How long has this been going on? Can you get an appointment soon to see your family Dr.,a Psychiatrist or counselor?
I your really worried its a psychological disorder go get tested or talk to a therapist or a psychologist.
These "crazy thoughts" are you in control of them because there's this thing called racing thoughts were thoughts jus come through your head and you can't stop them.
Good luck. If your really worried consider getting some help.
I've taken all your advice into consideration & will probably seek help. Thanks so much
