How do you focus on the positive when something triggers anxiety?

Know that you are in control of your situation and you got it. Remind yourself that you are strong and capable. You will get over this bump in the road. It's a part of life that sucks but you will accomplish your goals. Take some time on your own to just reflect on why this is stressing you out. It's ok to cry and worry about it, but make sure that you don't let that consume you. Pretend like you are your own therapist and be proud of yourself. I know that it is hard, but once you come out of this, you will feel stronger and all the more proud of yourself.
