<p>What Northstarmom and the other posters urging you to seek mental health evaluation asap said! (I also agree that an LD assessment would be a good idea, but not yet. The young man's mood, his depression and possible suicidality, are the paramount concerns here. Also, his emotional state could affect his performance on the LD evaluation.)</p>
<p>The combination of your son's apparent depression and emotional meltdowns, his mood swings, and his statement that he doesn't want to go on suggest that you might have an emergency situation here. Under these circumstances, it is OK for you, as parent, to take decisive action to have your son evaluated, not only to find out what is going on emotionally, but even more importantly in the short run, to make sure he's not at risk for harming himself. </p>
<p>People who are depressed tend to believe that nothing can or will ever help them, and can't even begin to envision themselves feeling better. This being the case, the prospect of seeing a therapist may not seem to offer any hope, and it's not surprising that your son is not enthused. Please use whatever means are available to you to get him to a mental health professional -- no matter what your son says about going -- if only to determine if there is an immediate risk. Please get several referrals from your GP and start making calls to set up the soonest possible appointment right now. Be sure the mental health folks understand the urgency. A specialist in depression would be great, but any competent mental health professional in the disciplines that have been mentioned is going to be able to help you.</p>
<p>The physical assessment that's been suggested also needs to be set up asap, but a mental health assessment of risk is the most critical.</p>
