It does Cire. I had also taken a greater sum of time for me to start exercising seriously, like every week 4 times. This will make you feel better. The joy itself could only last a couple of hours but you'll start to feel you'll be able to have some sort of satisfaction back and that changes everything. I started in between 3 to five months. Missed some of the 'classes' but persisted and it worked.
Hobbies, anything that may take out of the house and distract yourself. It could be movies, dating, reading, travelling etc. You'll find something you used to like. I remembered I used to really like building small 'revell' airplanes and painting them was very fun tons of years ago, now I try doing that with my son.
Are you planning you thinking about getting into a relationship. That has also been a good thing for most people, finding a good friend, dating. Or simply going out. Don't go to bars or clubs -- try open spaces, parks, gym, shopping. Do a brainstorm with what would you like to be doing now and find something you enjoy doing. I know it's not that easy and we are all weared out but remember that now the more you think about your quitting process more difficult it is to start.
Choose something simple and establish a goal for the week. Even you have start by walking around the block or getting some sun, changing your eating habits. We all know you are strong, now it's time to relax and avoid this normal lethargic phase we have sometimes. Don't let it be fed by not doing anything about it. You should be physically okay now, so one day at a time! And baby steps.
But it's for the best.
