Re. tips, I just remembered something I learned in therapy that I at least found useful. I don't know what you're like, but I have a terrible time accepting help. Very independent, very "I got this". And one thing I really liked learning was that a. people are typically offering things that are easy for them to offer. Like things that come easily to them (e.g. listening), they have an abundance of, or that are no effort for them (e.g. cook you something or drive you somewhere). People aren't offering things that are a lot of effort or out of their way. That put me at ease.
And b, when I say "no" to someone's offer to help (or maybe refuse to ask for help entirely), I'm not aiding them. 'Cause people draw satisfaction and feel good and needed when they're able to help you, so refusing help is actively denying them of that.

For me, it was a thing, and I was just reminded of it by a podcast, thought I'd share. :)
