Hi Lisa: I am almost constantly depressed as a result of PTSD after being caught in a fire. This has led to agoraphobia and of course, depression. I am a senior and have trouble getting up from low chairs, which makes it very hard for me to go out and eat, because mostly those chairs are too low for me to get up and out of them, so I do not get out much and I am very, very lonely--thus the depression that I cannot seem to shake.
