I would start off with paint for the cabinets and new hardware,will make the biggest difference.

I have seen much worse. Paint can do wonders if you are on a very limited budget. Paint the cabinets, paint the walls, remove from the walls and counters leaving only what is necessary or truly loved. Place a cheerful curtain in front of your pantry shelves. A pretty picture above the sink. Even plastic baskets which you can pull out then look at contents in your lower cabinets will help you. I like the large window opening and the counter below it. Get rid of visual clutter and add happy colors!

If you're looking for a temporary fix, change the cabinet hardware and paint the walls a warm mossy green. Change the shutters to blinds to match the walls. For storage on the top of the fridge, get a stand alone storage unit. Measure twice, buy once! If you want to cover up the pantry, get bifold doors. Develop a long term plan, including timeline, budget, ideas, and vendors.

Yep, it's bad. What are you willing to do? Do you have a renovation budget?
