What is your toxic trait ?

Maybe I'm toxic but I don't think either of the things you listed are toxic. I think cutting people off can be a sign of maintaining healthy boundaries for yourself. Testing to see if people will lie is a great way of judging someone's character.
My toxic trait is I think it's okay to make fun of people online if they've proven themselves to be horrible humans.

I’m with you on the second one, I almost always know the truth or can tell somethings fishy and start investigating. I’m a huge over-thinker.

The first one, I can give too many chances, but not everyone gets that.

I had a bit of an anger problem and i was chanelling it in the wrong way. But i've come a long way. I am extremely proud of myself.

i do that too..

I'm always prepared to never talk to anyone again. I've gotten used to the inevitability of people being gone or screwing up and passing through so I let myself be ok with it and move forward.

I often react to stressful situations and unexpected problems with anger and frustration.

I get attached to people too easily.

my traits aren't toxic, they're venomous
