I have to admit

I'm scared. I'm so scared of everything. I think I read too many stories and my GAD certainly doesn't help... but my heart lives on the outside of my body. Running near the sharp corner, swimming in the pool, climbing up the stairs. My brain makes me see the worst scenario. I literally have to close my eyes hard or shake my body to escape the thoughts. I was at the park with a friend today and can not understand how she can be so relaxed. Letting her 5 year old run ahead out sight, her 1 year old stand on a 3 foot tall concrete wall. I will never be that relaced. I can't let the most precious thing I have get hurt. I try to trust in God, that He will protect my son (with my common sense as a mother...), but I know things happen all the time that parents don't expect. I can't handle these detailed graphic scenarios anymore. Is it just me? My counselor says I need to replace the bad images with good ones, I try but it takes a lot of energy, she said anxiety meds probably won't help.
