I'm having difficulty deciding whether to stay here for most of the rest of the year or go back to be ALONE while getting my house fixed from a water leak/small mold issue that I discovered was in place when I left the end of October that will take 5 or 6 days to repair by repiping the whole house. It would create me being alone for the holidays by doing the RESPONSIBLE thing or just "trust the Universe" that all will be well and schedule beyond obscene out of pocket repair cost job for 6-7 weeks from now when we can travel back to Houston together. I've been cogitating on this for many days and just had a friend go in the house yesterday to check the bathrooms and bedroom for any smell, water and visible mold. He said all appears ok. Water is off to the house btw.
I can't seem to get over the anxiety and feel like I'm potentially putting my home (future needed money situation) at serious potential risk.
I get very agitated in these situations being 'what feels like" being an adult and doing the "grown up" thing.
Any suggestions or input would be gratefully welcome.

Thank you.
It sounds like you are currently away from that house if I'm reading this correctly. Do you need to be onsite while the repairs are underway? Having all the pipes replaced is holy-crap do I need a HELOC money. I remember hearing about copper thieves going into vacant or under construction houses to get all the pipes out, which did six figure level damage. That was also a lot of wall damage, too, but I can't imagine that the plumbing alone wouldn't be a MAJOR part, especially considering the cost of the materials on top of labor.
I know mold can be really problematic for some people. It's not good for anyone's lungs, but some people are allergic and could go into anaphylaxis. The other concern having to do with spending the holidays alone is a significant one, too.
I have spent entire holiday seasons alone, as in thanksgiving, Christmas, and NYE all in a row. It is pretty awful. I even accepted some invitations to do thanksgiving with friends but I felt out of place with it being mostly people I had never met and they were having an intimate family thing while I felt like a third wheel. I don't even like holidays and I hate that. On the bright side, I did have the hot tub in the apartment complex all to myself. This was before I knew that going into a hot tub drunk was a Bad Idea. I was very, very drunk at the time, but that's what I did to cover up the loneliness. I can't imagine why the doctor said I should quit after looking at my insides... just kidding.
I cannot give you advice for lack of knowing all the variables, but what I would do in a similar situation is to look for a third (or fourth, and so on) option. I'd suggest having your family out to spend Thanksgiving there with you, but I also imagine that it would be prohibitively expensive to get airfare this close. Failing that, I would use a cost-benefit analysis CBT tool to sort out what matters the most.
