Now I slowly get back into healthier lifestyle and try to piece myself back together to something what once was.
It's very easy to write something like that especially after everything worked out well. Keep in mind there are many types of people and some of them will always land on top (I'd say those with the best networking skills, which I have zero).
I just want to stress something that is often missed. If you are feeling good in current status quo just think what kind of person you are, what skills you have, what is easy and what is hard. Don't change your life drastically until you get to know yourself well. You can't "power through" everything that happens and there's a level of suffering that makes it all not worth it in the end.
