I can't say if u have anxiety but I was once a victim of anxiety disorder.I used to get scared of things and my legs start shaking and heart palpitations. At first I thought it was due to weakness but later I found it was anxiety disorder. My doc gave me paxil and clonazepam. It started making me good.  But see it all depends on you. You have to set your mind positive. Because of this illness I had to quit my job. i was scared to get out of my house.After taking medicine I started getting some confidence. Than i started walking 2-3 hrs in the eve even though I used to fill like I was going to have panic attack  at some time but god willing it never happened. If i feel like having panic attack I used to take a deep breath and it helped. So all I can say is get medication, be positive and build confidence. It will take time but u'll be good. I don't know much about depression.

Feel better.
