I love your space! I love how natural, light and calming it feels. I love mix of modern furniture and curved furniture. I would not go crazy with the colours, but I would replace at least one of the mirrors near sofa with some art with a splash of colours. Nothing too wild to keep that calming feeling. I think some plants with rustic/vintage vibe would go nicely with your dining furniture and console tables. Something like geraniums:

The only item that might be a problem is the kitchen island. You have a modern apartment, with fairly modern/eclectic bookcase and couch, but the kitchen island is a different style. If you have an overall eclectic style that would work, but otherwise it may need to be switched out for a more modern style.

Jennifer, I think you know the issue here is more psychologically-related than interior design-related. My advice to you is to keep your goals inline with your values. As Donald said above: "If you want to be the kind of family that eats dinner at the table together every night then start doing it now." You're drawn to a minimalist decor? Make it happen. You start with the list of essential functions in your space (sleeping, working, eating, relaxing) then you equip each area accordingly. Nothing more. Which means you get rid of what doesn't serve one of these purposes. You mention you're a hoarder: find a way to stop that behaviour or else it could consume you and negatively impact your relationships. Things don't provide lasting soul-nourishing happiness. Relationship and experiences do. Chances are high your kid won't be interested in your childhood toys. Keep your top 5 favourite ones if you must, but no more than can fit on a small shelf. Boxes and boxes of makeup? Whatever for? You only have one face and makeup breeds bacteria so quickly. Delete Letgo and similar apps if they tempt you to buy random stuff you don't need. Instead of scrolling apps for random stuff to buy, do something else, for example, listening to short motivation inspiration videos like Mel Robbins, cleaning or exercising, etc. Any distraction to help you stay on course. Once you control the clutter, your space will make a lot more sense to you and decorating it will be easier. You can do this, Jennifer! :)

you have a good base. all you need are accessories. art. here are similar furniture ideas to yours, but look at the overall room I love something like this w/your white sofa and rug. some nice contrast. and the art and decor items all blend in well or something like this if you need something for the tv
