Toxic is relative. This is like aceton, some material will melt in contact with it and others don't. So when someone say you are toxic, don't take it for some absolute property you have. When someone say that about you, in the context you describe, it means (I guess) that you are expressing negative criticism which can negatively affect the team's morale or mood. The pertinence of the criticism is not directly in question. Trying to answer your question, the first point should be to verify the objective reality and true importance of the problem. Assuming the problem you reported is real, the second question is what could be done to solve it. There are things that can't be changed and the problem you are dealing with could be such type of problem. In this case keeping complaining about the problem is indeed toxic because it affects the team morale. So to stop being toxic, you should stop any behaviour that affects morale of your team, and do whatever can raise the morale of the team. One way to do that is to find new ways to make the best of the situation if you can't change it. The key word is adapt. Help your team and yourself to adapt to the situation. The minimal action is to simple don't talk about the problem anymore. Everybody knows about the problem, so stop pushing with your finger where it hurts. A minimal proactive action could be to make funny jokes (not sarcastic) about the situation. This reliefs the stress and the negative feeling. Finally, the most usefull proactive action is to find news ways and work methods to minimize the burden of the problem. If you don't stand the burden yourself, considere swithching work instead of making life harder to your colleagues.
