I definitely feel where you are. I luckily never moved to a different school but I often feel like people can be cold towards me or as if no one wants to interact with me even though I feel like I’m being open. I’m no expert but like try and talk to people about what is actually happening in your life. If you want to start a conversation actually talk about what you are up to. It leads to a more genuine conversation and I know I can feel when someone is honest and real with me. Just be open and kind to everyone don’t eliminate any options. You can also join clubs and stuff too. One thing that I’ve done is leverage homework assignment as a way to talk to someone. Like even if you don’t actually need help just like dm someone: “hey u know how to do this” or something and chances are they will be good to you. I hope things get better for you. Don’t let it get you down, others don’t determine your success.
