As above . U need to see u pcp for evaluation and work up . It seems u have sever insnia may be related to substance use disorder or mental health condition . Do not wait see u physician asap.
Look . Look for a free or low income clinic nearby. This is serious and you do need professional help and perhaps prescription medication.
