Excessive empathy and always being kind no matter what. This is coming from someone who used to deal with this problem all the time. I was a people-pleaser when I was younger due to an abusive upbringing, leading me to project my issues onto my personal life. I thought that it was the only thing about myself that was worth sticking around for. Turns out, it did my self-image, my personal relationships, and my happiness a lot more damage than it ever would do anyone any fucking good.

Being kind and having empathy for people is very important, hell, it's vital. But there is very much a thing as having too much of it, to the point where it harms you and harms others.
