You're not alone, man. Alone is solitary confinement for something you didn't do.
But alright, maybe you feel that way and can't help it and you probably know why too - bad habits, lack of initiative, cruel people in your life. You might hear this and dismiss it because you hear it all the time, but seriously: hit the gym. It really works and unlike all the gym bros I'll tell you why it works. The simplest 30 minute load on your body releases adrenaline and a whole bunch of other chemicals which make you feel good for a few hours afterwards. You do need to work a little bit harder. The first time you go, you'll get nauseous from the overload but once you're done, you'll get that rush. Pick a gym where you can shower afterwards. Make it once a week at first and keep going and you'll find yourself going 2-3 times a week as the rush wears off. Don't expect "gains" you'll be the same flabby self 1-2 months in, but will see improvement if you keep at it. Better cardio, weight loss, better muscle tone, all on your own terms.
You can keep all your bad habits as long as you establish this one good one.
Here's another tip: you probably live in a city and when you walk outside, there's rubbish everywhere. Buy a box of latex gloves, and every odd morning when you go outside to go to the metro or to get a coffee, put on a glove, grab an old shopping bag and fill it with rubbish from the street as you go. People will look at you like a fool, but don't mind them. You don't have to pick up every ciggie butt, just the big things that stand out. When you get to your destination, slip off the glove into the bag, tie it up and put it in the bin. Again, no need to get obsessive about it, do this every odd day or so or when convenient (i.e. if it's horizontal rain outside, maybe not the day for this). You might not see any improvement, the filthy people in your neighborhood will shit up your street faster than you can blink. But that's not the point, the point is that you tried and maybe you made other people think about it too.
The reason these things work is because they are physical activities that take your mind off the problems in your life. They won't make you happy, but they will make a positive difference. No-one has to know you do this, there is no need to post online about it or tell your friends, just do it.
