I'm sorry that this happened to you. I know very well how the unkindness of another can be the source of days/weeks of replaying it in mind, feeling the hurt all the same. I don't know you well, but with depression I know how much effort it can take to follow through on things like sending out resumes as you mention and just trying to make it through the day. You are doing the best you can and need support, not unfair judgements.
