You may have a sex addiction, and you need to get help as soon as possible. If you cannot drive to the appointments, you can contact the department of human services. Or, after you apply for outpatient therapy (and psychiatrist) at your nearest center, you can ask if you can have assistant transportation. I had to use the service while attending a mental facility school. I was around mostly the elderly, but they take in people with mental health issues that cannot get themselves help.

Just go out there, and treat your self-destructive issues before you go further downhill and hurt yourself.
