Hi, ACT10Npack.
I am 2 years 7+months sober - don't know is it qualified as long-term though - but I will chime in.
Looking back I would worry less about "what if.., how I am going to handle this or that" - I would spare myself lots energy wasted for useless freaking out.
Time proved that everything was going at the right pace. When it's time to face an issue - I will find a way or power to work it out. Sometimes it's harder, but still doable.
So, my advice would be - one day at a time never fails.
Focus on the best you can do today. When tomorrow comes - there will be way too.
Best wishes to you.
