Reviewing and Reordering

Today when I stopped by Marge Lewis's home with the intent of sitting with her for five hours, feeling ever more useless as she takes over the management of her life, I found her son there fixing things.  Marge told me she now wears a monitor that will let her signal if she needs help.  I hoped for this day and expected it to come since she is so self reliant and upbeat.  However I need to decide my path forward.  For the past several months I have had two obligations that kept me from making plans to travel and somewhat inhibited other activities.  I had agreed to help Marge a couple of evenings a week when she came home from a nursing home and began to recuperate.  I was paid $130 a week for virtually just sitting around for the past few months.  I will try to keep in touch with her.  I think it would be fun to make puzzles of some of the pictures I have painted and challenge her to finish them.
In addition, this coming spring I hope my son David and his family will move out.  I haven't minded most of the aspects of their living here, but I have felt encroached upon by all of David's stuff.
The loss of the small job with Marge and the rent from David will make a difference of a little more than $900 per month in my income.
In the past few months I have been frivolous in spending.  Some projects and purchases were wise, such as a new chest freezer to accommodate the meat bargains that help to keep my Carnivore Diet relatively cheap.  I got a good deal on the freezer and I like the way it fits my kitchen after a bit of carpentry work.  I also feel I will get good service from the trailer that my grandsons put together.  On the other hand I have spent money on other things that I could easily have done without. 
These are some of the fixed expenses that I need to figure into a more conservative budget going forward:
Donations: Tithing plus donations of $200 a month which should add up to around $400 a month
Food and Sundries: About $10 a day coming to around $300 a month
Utilities: $300 in winter, $100 in summer.  Average $200 monthly.
Gas and Car Care:  Around $100 with normal travel and weekly trip to Bountiful.
Insurance:  $50 a month for car.
Taxes: $500 monthly amortized for Fed, State, County, Duschesne.
Helpers: $180 month for grandkids helping.
Gifts etc. $50 monthly.
Total: $1880 for what I consider irreducible expenses.
Income: $1500 from alimony, $800 from mortgage, $120 from SS.  Total $2420
This leaves about $540 for saving, art, electronic replacement and emergency fund.
$240 should go into savings each month and $300 into emergency fund. 
Live it and add as necessary.
I am grateful for this opportunity to put on the brakes and take account.
