Can you share with me how to get rid of my anxiety and overthinking mind? Because I am so scared.

Try to monitor, observe, track or trace what triggers your anxiety. It's hard to calm down your mind when you got triggered but you need to hold and work on your breathing, When I got attacked I go to youtube, to listen for binaural audios with visual calming meditations like psychedelic visuals. It's hard but it help a bit to empty clear my mind. If you have energy left, try to get up in the morning to get sunlight and drink plenty water, and try to look how you can boost your moods so you can take back control and power with your mind.

What always helps me when in a situation that brings anxiety or heavy thoughts that do not seem to settle is asking myself "will this even matter in 5 years?" If it doesn't, I realize how light the weight of the situation is and that it is just temporary. So I don't need to spend any more time and emotions on it than what is minimally necessary. I think it is still important however to let yourself ride the feelings out, but at least then you would be aware of the gravity of the situation, you would be aware that it is not as bad as it feels
