I never know what to do anymore.. .

So much is always happening.  I feel like I can't think strait anymore.  It's so over complicated and I am lost with what to do, but my parents are no help.  They think that any of the things I want to do are stupid.  They never take the time to listen to me, no one does.  I feel so lost and alone.  My mind is raceing, and it won't slow down.  It's like I'm stuck on a roller coaster on a merry-go-round.  Everything is so up and down.. and my mind is spinning .. but its not so merry.  It's like I am slipping off.. and I can't get back up.  I have even started doing drugs a bit again... nothing too hard core.  Just otc back meds and some majuana.  I do however have other stuff still... and I am afraid I am going to slip back into my old habits of drug use.
