Eventually, I think, it is your responsibility not to allow others to manipulate you. Do not allow yourself to get driven too easily with the flow. Check the facts and pay attention to signs. You cannot change others, or ask them to change.

For now I suggest to take an alone time voluntarily, and think about all these experiences that happened, and see how you can move on. If in the moment of clarity you decided that your friends are manipulative and competitive in a rude way, you need to re-evaluate your relationship with them.
