depression
"After a couple weeks I felt no change either positive or negative.  After a month to 2 months I felt somewhat better.  After 3-4 months I felt better than I had in a very long time.  Life changing better.  But now after 5-6 months my brain feels very foggy and I feel very emotionally numb.  I can't feel any negative emotions at all which can actually be very frustrating and confusing.  Don't want to change medication as it has helped so much with mood so I'm hoping the numbness will subside...And may be willing to tough it out since feeling numb is better than feeling depressed."
