Asked to be on my temple board, but I have spiritual doubts

So I’ve been going through a bit of a crisis of the soul. I am looking for more ways to get closer to G-d and to be observant and it feels urgent to me. I belong to a reform temple which is not very spiritual at all, but it is a good community for my family, because my wife is not Jewish and, by non-Reform Jewish law, our children would not be considered Jewish and might not be accepted at a conservative or Orthodox temple.

So, somewhat out of the blue today, someone from my temple called and asked if I could serve on the Temple Board as a VP to help plan events and bring in new families. A few months ago, I would have said “great! sign me up.” Because I like helping people and I have lots of ideas.

But lately, I feel like I need something spiritual that I’m not getting from my temple. I need to feel like I have an eternal soul and I need to feel a connection to G-d. I’ve been watching a lot of videos from more religious folks like Rabbi Shais Taub and that is starting to attract me to see if I can do more and be more in my observance.

But OTOH, I’m not sure there’s any other type of place for me and I haven’t exactly found another temple yet. I just feel like life is passing me by and I need more in my Jewish journey.

Granted, and this is a problem whether I take the board position or not, I’m not sure I’d find another community that would accept my family and be more religious at the same time. And my wife and kids are not in favor of moving to a different place or me trying to do something like keep kosher or keep sabbath.

Before you ask, no the rabbi we have is not the kind of person I could discuss this with. She’s not very friendly and she’s very material and literal. I don’t think soul things are her kind of things.

I just feel like my soul is empty, I’m depressed about it and I don’t want to grow old and die this way.
