Good to see Simon get some help, and that he has good friends that care about him. Being an actor in general is a hard job. you may get paid decently well, but your out and about for a good chunk out of the year working, sometimes far far away from home. Makes it hard to keep friends, and even family. "I'm going to be in Abu Dabi for 3 months.. sorry.."
You hope that you have good co workers/actors that are freindly, and can support each other, and have fun doing the job. Maybe Simon, and others, hit a hard patch where there burning the candle at both ends, and nobody around for support. Humans are social creatures, no matter how shy or anti social you are.
I'm guessing that maybe, Simon was a happy person, wanting to share his happyness with others thru jokes, and then somewhere down the line, he looked back and seen that, yes I'm successful, but how happy am I? Do I have a girlfreind/wife/other to talk to, confide in. just the act of being held is a huge thing.
So I hope other actors ( and people in general, lots of jobs that take you away from family/freinds) get help if they need it, be vocal to a freind, even a co worker that you are depressed, or have a problem.
Even if it isn't clinical, or an illness, people have bad days/weeks/months etc. and get down. The happiest person you know has down days. Do some soul searching, find out what is missing from life, and do your best to fill the void as best you can
