I am not certain that a lack of motivation is your main problem. More likely it is the fact that you are dealing with very challenging life circumstances. According to your letter, you have no home, no job and no support from your family. Both your mother and father are unstable. The problem is not you; it is your life circumstances. Faced with such circumstances, virtually anyone would be struggling.
I would encourage you to contact your local community mental health center. They can assist you in the following ways: helping you to find housing, a job, income assistance and by referring you to the appropriate mental health professionals.
Having a secure place to live is a basic life necessity. Without it, it’s nearly impossible to focus on other areas of your life. I hope that you will consider my advice and contact your local community mental health center. They can help you to get your life back on track. Please take care.
