Requiring motivation

My issue is that I have been out of work for three years and have been working on and off before then. I will not use anxiety as an excuse, however I just cant get my body to move and be more pro active want to actuall physically move from the spot where I felt the most secure. People around me tell me that you have to do something start going excersizing and start going out more often. But all I do is eat,sleep and drink and watch tvshows or be on the lap top I cant seem to stop myself from feeling stuck.

This hold is a psychological hold which is somewhat hard for me to get out of.And I feel frustrated and anxious because of the feeling that i should be employed and have my shit together by now.

Like I said I am good at giving advice but cant seem to do that for myself and I feel I have a lack of motivation as confidence, for a person who has confidence, I guess I should state that i doubt myself constantly

I used to work out but due to back pain i stopped and played football nd then stopped that too and I am anti social in away due to feeling embarassed of not being employed.
