If your thoughts do not give you peace, all kinds of negativity come to mind and you notice them, try to fight, explain, etc., then you give them strength with your energy. This is just like all kinds of information wars, where 2 sides strongly disagree and try to prove their truth. It turns out that the energy of both sides feeds that pendulum, which is wasted from one side to the other. The pendulum doesn't really care who wins or loses, all it needs is to waste energy (and if both sides just stopped feeding the pendulum, it would just stop and rust).
Pushing it aside/pretending it's not there is no good either, because everything remains, just pushed away and later starts to rise to the surface again. And anyway, there's a much simpler way to deal with it: all you have to do is respond to those thoughts as you would an unawakened, pessimistic friend. Understand that this is the subjective truth of those thoughts (that pessimistic friend) according to their current vibrational level. Accept it and let it be. Because when the vibration rises, everything will automatically change. In time, that friend will change their vibrations if they want to. In time, your unfed negative thoughts will have to adapt to the changing vibrations or starve to death.
P.S. don't go to war with pessimistic friends either, don't force anything, change yourself, and give them love. When they see you beaming and they want what you have, they will ask you to tell them what you do :)
