I figured I had OCD but not that bad and I suffered from anxiety and depression on and off all of my life. But, this latest illness really got me feeling very anxious and depressed. I tried Paxil but I built up a tolerance to it. After some time, like months of dealing with this for quite some time, I finally ran upon Lexapro; Which from what I've read works well. Why has this hit me later in life like this I'm 59 and appear mid forty's. My question is why have I got so ill with anxiety and depression this time? I have lost a lot of weight as well. Hoping this lexapro works for me. And why has this happened to me now so bad? I dread every day. Can anyone one respond to this?
