在英语中，表达“我还是只习惯一个人”可以有多种方式，以下是一些常见的英文表达和相应的情境使用：
1. I’m still used to being on my own
这种表达直接而简洁，适用于描述你习惯于独自生活，不依赖他人。
例句： “I moved to a new city for work, and I’m still used to being on my own. It’s been quite challenging but also liberating.”
2. I’m more comfortable being alone
这种表达强调的是你对独处的偏好，而不是不习惯与他人相处。
例句： “My friends often invite me out, but I’m more comfortable being alone. I find that I have more time to think and relax when I’m by myself.”
3. I’m just not used to having company
这种表达适用于你刚刚开始独自生活，或者是在一段关系中刚刚分开。
例句： “After my breakup, I was really struggling. I’m just not used to having company, and it’s been tough to adjust.”
4. I prefer my own company
这种表达比直接说“我习惯一个人”更加委婉，适用于你更喜欢独处的情况。
例句： “Some people might find it strange, but I prefer my own company. It’s just how I am.”
5. I’m still getting used to it
这种表达适用于你正在适应独处的生活，但还没有完全习惯。
例句： “Living alone is a big change for me. I’m still getting used to it, but I’m enjoying the independence.”
6. I’m still finding my groove as a solo dweller
这种表达更加口语化，适用于描述你正在享受独处的自由，但还在探索如何最好地适应这种生活方式。
例句： “The freedom of living alone is great, but I’m still finding my groove as a solo dweller. It’s all about finding that balance between solitude and socializing.”
在日常生活中，根据不同的情境和语境，你可以选择最合适的表达来描述自己习惯独处的状态。记住，每个人的生活方式都是独特的，用英语表达自己的习惯时，也要保持真实和个性化。
