Yeah....it's pretty lonely at times (especially now) when you leave the group. That's why most stay with it even when it isn't making sense to them.
Right now with the covid19 distancing everyone is feeling a lot like what you're feeling but at least they know they can go back to their regular life once it's over.
In regard to your life vs death feelings, you're not the first person to feel that way nor, unfortunately will you be the last. You are in emotional pain and it's natural for you to want it to stop. Like most people you really want to live but you want the pain to stop and you don't have the skills YET to know how to go about it.
What you're going through now is kind of like physical exercise, you can't get stronger until you go through the pain and strain. No one can do it for you but they can encourage you to keep going and help you remember that everything is difficult before it becomes easy.
It may be helpful to stop looking back on how things were in your old life and comparing them to how things are now. It's too soon for that. We tend to look back on things and remember them better than what they really were. At the same time it may be helpful not to look to far into the future into the unknown. Right now odds are you won't be able to come up with anything hopeful about the future right now because there are too many unknowns. Looking too far into the future will make you feel worried and hopeless.
Try to stay in the moment as much as possible and trust that if you put one foot in front of the other and keep your nose pointed toward the things you want and your mind off of the things you don't want, you will get where you want to be.
Get a notebook and when you catch yourself worrying or ruminating on negative thoughts, write them down and write out a few possible solutions and two or three things you can do tomorrow to move you closer to where you want to be. Put the notebook aside and resist thinking about those things and find comfort in the fact that you have a plan for tomorrow, no matter how small it may seem.
