Ok. I'll try to take a stab but all it is is my opinion.

You say your anxiety and irratablility is through the roof. So, I'd say that's not quite " stable " for lack of better word. Not that you are not. So there are ways to deal with those two things outside of overmedicating yourself. Because overmedicating is dangerous and will not bring content or happiness. I completely do understand the desire to be numb from it all tho. But it's a temporary solution.

What else in your life could be lacking that might be contributing to this empty feeling? Purpose, plans, goals, connectedness, sociability, spirituality, those are just a few things off the top of my head. Of coarse I don't know the answers for you. But I do think in these days we really neglect nourishing our whole selves. We are busy, many other demands and we just don't even have time to think about this stuff. Or at least it's how it seems. I do think when we feel like an empty vessle it is usually because we are because we are trying to fill a hole with stuff that doesnt fit. So the hole never gets filled. I think this is where true happiness and feeling content and nourished, healthy lies.

Anyways you may agree or not, just another avenue to explore. I wish you well.
