More insights about my progressed Moon in Pisces...
...it has become pure suckitude.
I've been trying to figure out for weeks why I feel so. goddamned. vulnerable.
It is terrible. I have not felt this bad in years. This consistently scared. As a proud natal Moon in Capricorn, I typically deal with insecurity by burying it. That used to work. Lately, not working at all. And flower essences, gems, meditation all no go for emotional fortification.
Last night I figured it out. I feel more vulnerable than ever in my life because I am. What came through to me was that over the past two years, one by one, the things that passed for my security in life disappeared. Parents, sibling, surrogate grandmother, and eventually, a strong, older man who had been a consistent presence in my life for six years. (He kind of went crazy, alienated many friends and affectionates, including me, and it really hurt watching that happen.)
I've noticed that one manifestation of Pisces energies involves endings. I just didn't expect everything to end.

I'm so sorry that things suck right now. Keep your head up. Things will get better. 
I hope things get better quickly
you might want to try for what it is worth....
You might imagine mating with your progressed moon.
The reason I say this is that I have a natal moon in Pisces, plus a whole bunch else there and almost all my significant others end up having Cap moons. (Apparently, I'm rather irresistible to them and they work well for me.)
As you probably know, Capricorn is an uncomfortable place for the emotional moon. You are used to this as it is natal for you, but the lunar planet loves watery Pisces and so does dry Capricorn. I believe this could be a good thing. Not sure about the rest of your chart, But Cap moon and Pisces moon together has been wonderful in my life.
Sorry the transition has felt yucky.
I have lots of dependability in my chart so it balances out and having Taurus rising, I tend to want solid folk as friends and lovers. I really understand how that lack of trust could make you skittish. Surrounding you in love and light and stability. 
it's a like a free roller coaster! everyday! 
... yes, i can understand your mistrust, then.
Been there a few times...
The key phrase is this: "the things that passed for my security"
I don't need to tell you that there is no security in others. And everything hasn't ended because you are still here with us. Your life goes on, your spirit goes on. And you are strong. Stronger than you know. And we are all one, so they haven't really left. They're just around the corner (or in the case of your strong older man, gone 'round the bend 
)
This too shall pass. Your void will be filled. Inhale and fill it with your own spirit
