My spouse just found out she has some issues and I don’t know what to do.

My spouse was recently diagnosed with mild depression and ADHD. I am happy that they are getting help. We have been married for seven years. Before we knew what was wrong I thought they were just moody and a night owl but some of that has been cleared up. I honestly was able to mitigate and deal with the emotions and everything else but now we have two small kids and I find myself being drained working full time, taking care of the house and watching our kids when my spouse works. I just don’t know if I can continue on this path without losing my job or losing my spouse. I will always put the kids first. Has anyone dealt with this and how did you handle it. Did you stay and just keep helping them? Did you leave so you could prioritize your health and children? Did you stay and inevitably the relationship ended even though you tried everything? Please help me if you have any experience with this.
