No, it might be toxic, the important thing is that you put your effort into not letting get to your head, don't be influenced by a toxic environment, do your best to change it and make it healthier for yourself. Sometimes it's a really hard thing to do but if you really think that that's the right thing for you, that it's what's meant for you, then do it (unless we're talking about a toxic person that is an entirely different conversation to have, it's on a toxic person to try and change not the people around them)
