I would absolutely mention the social anxiety. From quite some posts you wrote I read how much you struggle and this is really something that can and "should" be fixed (I deliberately choose not too visit friends too often and I am very much comfortable with isolation, but I have no social anxiety even though I had during my first yearslong severe depression and years after that). I had to discover all the things to cope by myself, but I am sure a therapist can really help you in no-time (relatively speaking). It also helps you to rise from depression much quicker.

The "plans" I wouldn't talk about, personally, but if not telling might endanger you any time in the future, I would just be open, also mentioning the importance of the "plans" for you. The (maybe delusional) importance is what matters most.
