I understand that fear and anxiety can be really hard to deal with especially if you also have Depression.
I read this really interesting abstract today. It is said that there are three fundemental fears. The fear of injury, the fear of anxiety, and the fear of negative evaluation. The ASI ( Anxiety sensitivity index) measures Individual differences in the fear of anxiety responses. Anxiety sensitivity is strongly associated with fearfullness. (James Reiss: clinical psychology review 1991)
A better understanding of the causes of PTSD may lead to more effective treatments. Available research suggests that anxiety sensitivity may play an important role and that treatments that directly target anxiety sensitivity (such as interoceptive exposure) may improve outcome, particularly if these treatments are implemented before commencing trauma-related exposure therapy. (Steven Taylor Journal of Cognitive Psychology 2003)
Interoceptive exposure aims to recreate internal physical sensations within a patient in a controlled environment. Here is a really good article :

Depression and PTSD is commonly linked. Therefore treatement for both is recommended. The symptoms of depression can be personally recognised in most people suffering, we are not alone. So combine those with symptoms of anxiety it is not suprising we do not function well at present.
Here is something I read earlier :

Ironically it is this depression and anxiety that influences your thoughts and behaviour and so you stop yourself going forward. Thinking there is no going forward fuels your depression and anxiety. And so things repeat themselves over again. Because they both fuel each other it makes sense to at least work on one to improve the other. The final decision and choice has to be yours in the end. I think that makes sense.
I'm not sure if what I have said has any bearings for you but I find the more I understand about it the more certain things start to make sense and so there is less confusion for me to worry about too. I know work on my depression and symptoms and this helps me go forward and definately improve in ways, slowely but surely. :)
best wishes
