Your line “I realize it’s not the whole thing that needs to be taken on, just right now” reminds me of the old cliché: How do you eat an elephant? One bite at a time!

I am truly sorry that your boyfriend and mom contribute a large amount of stress to your life. Those should be the two greatest supports for you to lean on. One of them you can do something about and one you’re stuck with. However, even with your mom you can control the relationship. Just do so with thoughtfulness. You have greater power in your life than you know.

I sincerely hope the best for you.
