Strained Friendships

Hey, I need some guidance and if any of you know some Bible verses that would be a massive plus.

Recently, a coworker/friend of mine was having some anxieties in her life and kiiiind of took it out on me. I'm sure that even if she wasn't have some personal problems whe still would've felt upset by our conversation, but it really was a misunderstanding. That being said, I defended myself and we sort of left it at that. She apologized and said she understood we won't always feel the same about things and she shouldn't let that upset her, but it really got me thinking about, basically, how tired I am socially with my life.

However. Shes been abandoned and isolated for so long, I really enjoy her, but she's not my closest friend and I don't want to open a gateway to more arguments and I don't want to put in the effort to get closer to her by overcoming these obstacles together.

What do I do? Are there any lessons I could read upon to help?

Thank you
