Welcome! Posting here on gye and staying out of isolation can be a huge help regarding loneliness and depression. We sometimes feel depressed after a fall not realizing its the yetzer hara trying to stop us from learning from our past mistakes to move forward in life. He wants us to be sad and down because then we not only don't move forward, but we regress as well. You mention that in the past you made it 7 months clean. What methods did you use then? Maybe it would help to sit down and upgrade those ideas and make them stronger for the future. The name of the game is being proactive and taking this battle one day, even just one moment, at a time. Keep on posting! Hatzlacha raba in the job search, i understand that it can be very difficult, but be"h it'll all work out. You can do it!
