How to stop PMO if you actually work from home

Hi, long time ago I used to post here frequently, and I'm pretty ashamed almost two years ago of my previous posts in here I'm still stuck to this energy-time-confidence-LIFE draining harmful habit. What a pity.

I've struggled in the past, I've fought in the past -and don't get me wrong, I'll still fight for my goal to the end of days- but taking a look back at my posts, I seemed to have a stronger will power and a tendency to stick to my plans, stick towards my goals. To have discipline, basically. I no longer have that as far as I can see.

Back then I used to go to the gym every day, back then I used to force myself to go outside and interact with people; now days have gone by and things have changed, I work from home, I stay home all day long, maybe go out and do some activities from time to time, but I feel I'm depleted of all sanity, I feel I'm depleted of all confidence in myself, I objectify females way too much. I've ruined my potential personal both sentimental and professional relationships. I no longer have discipline. I no longer go to the gym as well, back then my world used to turn around it, at the point I considered I found my way in life, I was gonna study a career about personal training. I did none of that.

The thing is, I need to recover my life. I come here right after I watched this video, and in that movie he talks about going out to the world (rat park), making more than 1 friend who you actually have a bond with (I have that one friend, and I'm not really wanting to go out and make more, because he already knows my demons, he has already fought battles with me, both professional and personal as well). What am I supposed to do, if I must stick to my work from home, if it is what brings me quite a good amount of income for my life and my pleasures? How do I fight this battle now? I feel really upset, awkward and powerless. Throw some light at me fellows.
