Never done this before!! Hi All, need help with anxiety!!

I had bad anxiety but every so often. This time in my life is a little stressful. However I got the nexplanon just a few weeks ago and now I'm having an attack every other day if not EVERYDAY !! I feel like I'm being attacked by everyone! Extremely sensitive and crying. I have the shakes. I'm so down about stuff I would usually get over by now or handle much better overall.
