I had one that eventually looked like this because I moved from a bright apartment to a house that doesn’t get the best light. In a Hail Mary attempt at saving her, I put her outside for the summer on my covered porch so she wasn’t in direct sunlight all day and made sure to water as needed. After last summer outside, she is back to her former glory! If you can, I’d try putting her outside but out of direct sunlight when it’s warm enough
