worried... again

well James did his course and passed.  Turns out that it is not the end of the course though :(  He has to do a bunch of on line stuff and then 15 mock inspections and then another test before he will be licensed in Alberta to do home inspections.  Still worried though.  the last two part time jobs that he said he was excited about died really fast.  but he said that he enjoyed doing the mock inspection which is good.  So worried that he is only seeing the "good " parts like he did with the last two jobs.  i dont know how to show him to push through his fear.  He can't seem to get that far.  Yes he is better than he was a year ago or even two, but in my eyes, we have hit the hard wall and it doesn''t seem to be budging because he can't seem to push past this part.  I feel that he is still trying to find the job that wont cause him anxiety, not the power to overcome the anxiety so that he can work any job.  sigh.  nothing is easy of course.  hard work.  i was taught how to work very hard, and do work very hard for what I want.  I excersice very hard to hit my goal weight and body shape, i work 3 jobs to keep the bills paid and family sustained.  and I dont give up that much mostly, because my pride is very high, but I have learnt to push myself.  And overcome hardship.  How do you teach someone how to do that?  and that it hurts but can still be done?  his paralizing fear it just that, paralizeing.  So how do you teach someone that shuts down, to stand up and keep walking? breathing? trying?  when they just freeze?  Is it my job to teach him?  How much more can I give up before I have nothing left to give up?  another weekend of fun plans with friends done, because its to much work for him to do.  So he is to anxious about it, so he doesn't want to do it.  We have time, if he gives up computer time.  he plays a lot of on line games, like right now, and has been for the last hour, and hour we could have gotten the trailer ready.  But it was to much, so I had to cancel plans with a friend.  Do i leave him alone for the weekend and go enjoy myself?  will that hinder or help him?  I think hinder, so me and the kids give up fun times, because its to hard for him, or so he thinks, he wont even try!  And thats where I get mad.  if you tried and it doesn't work then I understand, might not like it, but if you ran out of time to get the trailer ready, even though you had 2 full days since your not working or anything, then at least you tried.  but when you just give up and say you can't.  I hate that.  how can someone ever be taught to just give up because it might be to hard?  what kind of life is that?  I just dont understand it.  how can you not want a weekend camping? enjoying the time away, no stress?  i am still a bit lost.
