Well, for me, ruins of any home/shrine mean something similar
...for me, structures that I hold dear in symbolism--a shrine or grandparental home that contained an alter to family--always had an inner symbolism that felt my inner sanctum in dreams that were intact.
Why don't you see if from one of your tarots you can find a similar picture of ruins or overgrown temple, if that is your focus? Or another suggestion below.
But you will see your own connections when you think of ruins. Usually it is best for the person to think of their associations. If you need tarot to assist, that's fine--but do a one-card pull of your favorite card deck or decks first to see if a random image and your dream 'connect'. My guess if you already did tarot and didn't like any of the layouts you are used to, could it be tarot isn't the way to interpret your dream?
In my own situation, I was able to analyze this--not certain, but the way you presented your work situation sounds almost like you already guessed an association between your dream and your thoughts.
For me, ruins:
Until I moved away, far away and felt my own essential self, joy and family connections were slipping away. The realization came from re-occurring dreams that ended with walking through rubble, seeing that even the shelters of my remembered cherished structures were just gone. I was 'picking up the pieces' and trying to see if I could salvage something.
Mind you, I was continuing to work more than my share of hours care-taking others for work and home. I think as I realized that over time, everything that I liked or cared about slipped away slowly...from days off, to entire weeks of vacations, joy, plans, time and quiet...made for me to realize that I saw my life in symbol as overgrown ruins from my mental imagery.
If what I say strikes a similar chord to you, may I suggest also something below?
Things were still growing probably for you in observance of the sacred, despite not observing outer aspects of holidays that you hold dear---but it probably is making your inner self a bit grumpy and a tad disgusted...that's my take at the information. That your inner goddess is intact is fine; but the core is feeling perhaps threatened or exposed because the time you used to observe for self and sacred isn't available?
How about trying to work one or two card draws a day in the early morning...and if that element of making 'sacred space' or a few minutes time for yourself assists, then perhaps your dreams will be more about growing in more peaceful settings...
Just some thoughts. Hope they help a little.

P.S. The artist for the Elemental Tarot (Caroline Smith)--if that is the one that you mean in your profile--has also a Moon Oracle with Lilith and here's the card/meaning--maybe it is helpful? Despite negative associations, it could be an association of feeling bleak or tired and stressed and having to pull strength from dark thoughts...so perhaps you need some self-nurturing before trying to exert yourself to necessary steps...
The Moon Oracle looks like a pretty and nurturing deck and has goddess associations as well as the strong meaning listed below--Does the Elemental have a Lilith/Lillith association that rings meaning for you?:
