all life choices have their bad side of the coin. your ‘no roots, doing my own thing flitting around’ idea was good for a while and now you’re seeing the downsides and envying all the people who took a different road. that sounds somewhat entitled - they didn’t get the sweet part od your deal, why should you get the sweet part of theirs? I think you need to work on this feeling that you always need to be feeling good and winning and everything going your way. just change what needs to be changed so that your kife suits you more, step by step, and stop feeling entitled to being happy all the time.
