clearer..is that a word?

So I've been going to this Intensive Outpatient Group for a few weeks now.  I can honestly say now that I can finally see in myself some improvement.  I can think and speak more clearly.  I can read my bible, which I haven't been able to do for a very long time.  And I can read other things, and do my homework from the group. 
Howwever, I still get tired alot and I still can't drive a car.  But that has more to do with being dizzy than anything else.  So it's not safe yet.  I haven't driven in about 5 years, exept for some practice for a few weeks about 6 months ago.
