Whenever I hear bad news about something from the past I just don't know how to handle it at all!
What is it about the past situation that causes it to affect you so deeply?
I have been asking myself that question many times.
It's understandable that unhealed past events cause negatively feelings for you now. You should try to understand the past situation and look at your present situation to move forward. Hanging on to past events will only create a burden for you to carry because you can't do anything to change it.
Shit, my depression is getting the best of me here and I don't know how to get out of it.
You should try to focus on the future or the positives of the past, instead of the negatives. If you dwell on things that you cannot fix, you'll find yourself going crazy.
