hi lola1, i'm an adult with the same issues as your child as of now, I'm no longer in school or work, but alot of the things that you explained led me to ssd right now as an adult, I don't mind about being on SSD, because it gives me time to rethink my life and just relax,
but it sounds like a mix of problems, such as sleep apnea, anxiety, perhaps a personality disorder, ptsd? and other related issues. Have you or your child gone though a traumatic event? such as divorce, or a family member or friend dying? or is someone close to your child going though hard times?
your child really does sound like my childhood and life right now. for me i lost my mom when i was 4 to diabetes, my dad left before i was born, and almost lost my brother to drugs (my brother went though same crap as me)
If your child has not been though a truamatic event it could be that hes being bullied at school or overstressed. It is not your fault at all. School especially High school was the most stressful time for me, it felt like i was alone or neglected, not from family, but from friends and seeing teen romance all over the school. it pissed me off bigtime as well, went home sick with migraines/flu like symptoms.
I'v went though complete hell in my childhood and job industry that i am sleeping all the time now, 16-20 hours a day and just pissed off at everyone (even though i act nice around other people) but i have so many emotions, anger, frustration,sadness,panic inside me that causes severe panic attacks and nightmares that are to the point of ripping someones head off. you may want to get him on ssd, just make sure that you he has past history of ptsd, anxiety, and alot more, i also suggest that you get a professional, non-profit organization, lawyer to help your child get on ssd, i was rejected twice, cause i tried doing it by myself.
