so so many... being dependent/alone/incapacitated when i get old.
being incapacitated/disfigured now (i know thats such a horrible thing to say )
being in a lot of pain.
being eventually rejected by everyone ive ever known.
waking up too late to the fact i didnt make the most of my life.
knowing that i irreversibly hurt someone.
finding out what the terror i sometimes feel is from.
being faced with my inmost thoughts and feelings.
losing my mum or my sister.
having a complete mental breakdown.
being unable to succeed in my career.
realising too late that ive never actually helped anyone or made life easier for them.
still feeling like this in 10/20/30 years.
thats all i can think of right now though im sure the list would go on if i thought about it.
