Bad Days - somethings wrong

For the last 3 days I'm been feeling really weird and get tired fast.  I've been doing a lost of sleeping.  I can read or get any motivation.  I need to work out to exercise but I can't do that.  My memory is going.  I feel very unstable when I'm walking - I wobble.  Sometime I'll run into the wall.   I just don't feel like I exist anymore.  My parents don't understand my illness because they have their own  problems of having Alzheimer's.  My brother is to busy and is only committed is own family.  I have to beg him to help me how and sometimes I get he's too busy.  I don't have any friends anymore.  My one friend we dismissed each other because she felt she wasn't getting any compassion from me about her problems.  I told her that I had problems enough and it was a trigger to near someone complaining, being angry and talk 100 miles to a minute.  My ears were going crazy.  She would blame for things when in turn she had the problem as well.  But not in here eyes.  I had to let go of the trigger. So now I'm alone.  What do I do where do I turn.  I need friends really bad.
