A trauma counsellor shouldn't be the first port of call for someone who has had massive damage, been in a coma and is having issues during recovery. Trauma counsellor are psych students who couldn't make it into masters and they are far from qualified to be dealing with this. This is forgetting the fact that something of this serious nature should be dealt with by the treating physician in the first place imo...
I think you dismiss the counselors a bit quickly, sure most of them dont have their masters, but this doesnt necessarily mean they dont know what they are doing. Its also generally a far whack cheaper and in my experience (and this is probably biased) they tend to not drag sessions out to make money off you.
In any case, i think the advice here is to seek help. Perhaps a referral from the hospital where he was initially treated would be a good idea. I am surprised they didnt mention or offer advice in this regard
