Not being enough

I know this thought can come up for all of us, but I feel that it has been with me for a very long time and I don’t know how to manage it.
I’m not enough for myself. I don’t reach the goals I want. I hate to see that I’m failing and failing. I am not satisfied with what I’ve achieved.
The same goes for my relationship.
I have a wonderful husband, but I can’t help but think that he should be more supportive, more attractive, he shouldn’t eat that much, he should listen to me when talking about weight-loss and urges.

It all comes down to the thought that I’m not satisfied. Not with him, not with life, not with myself.
How can I believe and practice more supporting thoughts and “deal with” the I’m not enough, I can’t be satisfied thoughts?

For my brain SCS teachings are sometimes conflicting. Love your body and love your life the way it is, BUT don’t eat what you want, don’t enjoy your food, don’t settle but set bigger and bigger goals.

It is also connected to satisfaction for me. I can’t be fully satisfied and want to have more but also have to be content with what is.

Thank you for your guidance.
