Prayer for Anxiety and Peace of Mind

Please pray for me. I have been very anxious and worried about my heart for 2 weeks now. I went yesterday to have some tests and lab work done because of a racing heart sensation. I suffer from depression and anxiety to the point that I become non-functional. I have 4 beautiful children and I don’t wont them to see me like this.

I need peace in my heart and mind. Please lift me up in prayer and deliver me from this bondage. Please help me accept whatever plan God has for me and may HIS will be done.
