Hi SadAndEmpty, hey you just tell us just as much, or as little, as you feel comfortable with, want or need to, we're still going to be here for you
And if you're not up to talking about things (or not talking much) e.g. if you're tired/if you're lacking energy or motivation, then that's absolutely fine too. We/I completely understand.........all in your own time

The work with your T though, she should allow you some control in where it's going/how far you go..........and if things are starting to feel difficult for you she should sense that and slow down the pace. But just as much if things are getting hard for you just don't hesitate in saying that. There should be no "clock ticking" as to how soon you move onto........how far you go with........
So she should be moving fairly slowly with it all. It might even help you feel more in control if she lets you know what she/you're going to be trying before the sessions, that way you're going to know what's coming and feel better able to go with it or to recognize when things might be going too far for you for the time being.
And maybe make sure with her that you have some "coping skills/techniques" to use for if things get hard e.g. if you begin feeling x you'll do............, or if you begin feeling y you'll do..........

And the alone time late at night............I know, not ideal with the tiredness already there, and lack of sleep which can just make depression even worse...........but if that's the only/best time you can get and you obviously need that, well priorities, hey??
