Boredom

It may sound cliche but exercise is the best if you can afford it go to the gym it will get you out the house and give you something to commit to. If you stick at for a few weeks you will see the difference and feel it and it will boost you even further. If you can afford then try running trust me if you have run before or it been a while it will be physically hard but again after a week or two you notice your body being able to go further and faster than the weeks before and you’ll feel amazing for it but do it for you don’t obsess over it do it for yourself and only yourself

Stay productive, either with doing chores around your house or hobbies that you can engross yourself in. Productive & creative hobbies that you can progress in - not things like gaming or binging a TV show all day.
