Just wanting to add another flavour of the same thing:
Maybe step back a bit first to go forward - Start with being kind to yourself - it’s ok to have those feelings of resentment, they make sense, they arise or are there because it’s natural, it’s what a feeling being ought to feel given who you are and your particular enculturation…that’s a great way to stop fighting it, it’s fine, it’s ok, nothing is going to go wrong just because you feel what you feel, certainly no worse if not no better….
Maybe things in your life really have sucked from a feeling being point of view and so it makes total sense that feeling resentful is one of your ways of being.
Is it happy and harmless? No, but that’s ok, we are not there yet (in this exploration), we are only at the point of stopping fighting being the feelings, fighting ourselves…for me this was a necessary step which then lifted the doors to feeling happy…
Yes these ways of being are habitual, but to experience that as a fact, embody (em-be?) Em-be your feelings…for you are them and they are you…Then you’ll have the choice, the choice of how you want to be…
Don’t try and skip to the end, it’s easy to try to, especially if you’re good at thinking things through, but the process is experiential, and might need a slow, gentle examination of your experience, lots of pauses, waiting for experiential answers to arise…and they will, with the intent and willingness and curiosity and desire to change. It’s totally doable - and I spent years stuck in the same boat also, wondering why I couldn’t make progress - relinquishing resenting life is so key and for obvious reasons
