Severe anxiety over the problems of OTHERS

Hi guys
I'm not completely aure I'm posting in the right forum since I don't know exactly what's going on, but here goes...
For 5 years I have had a clinical depression, classified as very severe when worst and moderate right now. It's probably secondary to my general anxiety disorder I'm told. I have been working on my self-esteem and using cbt to (amongst other things) stop feeling guilty about not helping other people, being somewhat of a people pleaser.
I now have a pretty balanced view on things where I formerly thought I was "at fault".
Now I told you my background without even knowing if it's connected to the problem in any way...

Here's my problem. Whenever someone I know goes through something hard I feel very bad. I have this huge lump of anxiety in my chest and " relapse" into worse anx/dep.
Some examples:
-One of my friends had a really bad experience with an abortion and I had this lump in my chest for three days afterwirds and it took me an additional week to "recover" to the level I was at before she told me.
-A (not even so close) friend told me about sexual abuse she had been the victim to 10 years ago. She was handling it well and wasn't even very upset when she told me. I still got the anxiety lump.
-I met a friend yesterday that I know has been feeling down and I could see him suffering much more than I had imagined. We were really close before so I can read him well and he was really suffering, feeling guilt, maybe even hating himself. I haven't been able to work since then (1,5 days since I saw him) because I've been feeling so bad.

Now in each of these cases I have done everything I can and that I've been asked to do. It's not guilt, and I can't shaka thr feeling because it's about someone else. I realize it's some form of extreme compassion but it can't be healthy since it disables me to the point where I'd be of no use to the person even if they needed any help. Does anyone recognize this?

It's Personal Distress.
