Belated congratualtions on your job! I hope it is working out well for you and things are improving.
It sounds like your husband is trying so make sure you are having conversations with what you need/want and ask him what he wants/needs, what your dreams are.
DH and I have been married for 24 yrs, there have been times it is more difficult, where I have put effort into remembering why I fell in love and then that reminds me why I married and what I love about my dh. We are the best of friends, I prefer to do things with him over anyone else. Most of the years have been wonderful, magical years, everyone should have that, but it is work at times and it takes both people making that effort. When people date, everyone makes the effort but as years go by in a marriage it is easy to just coast along and not put that same motivation into it.
My advice would be to make sure you and your husband are doing something together every week, it can be a walk in the woods, it can be shoveling snow and then having hot coca, taking a drive together. It doesn't have to be expensive, it doesn't have to be bought, it is time together to reinforce the connection to each other. Together make a romantic meal after kids go to bed or try a new dessert recipe together. Nothing complicated, just something to have fun with.
Your quilts are beautiful, truely beautiful. To create those quilts take a gift along with skill. I know, I have tried and mine look nothing like yours.

You should take really good, multiple pictures of a couple quilts and then list them on
ebay, on etsy. Get a paypal account first, then register with
ebay and etsy. Put a quilt up on each. Use a buy it now so you are setting the price or an auction but start the auction high enough that you don't lose money on it.
If you start feeling down again, please call someone or tell your dh or your father or his wife that you need to go talk to someone now or drive to a hospital and check yourself in. You are worth it, don't ever forget that. I will keep you in my prayers that life is continuing to improve for you and that you are happy. Many good thoughts for you and your family.
