Depression and anhedonia are almost one in the same and can also be applied to other conditions as well.

Once I was properly treated with meds it made it so much easier to tackle the agoraphobia you have. Being properly medicated will give you the motivation to tackle your anxiety problem which in turn lifts the depression or vice versa which equals recovering your happiness. If your are not feeling better in any area yet and are on meds I would get that re-evaluated so you can feel well enough to properly use CBT and other therapies to get you on the road to recovery. Like I said I am cheering for as I was once in your spot. You can friend me ,pm if you like. I know sometimes we have to hear it a million times to be reassured that you can overcome this.
