what is the best depression medicine to help with depression, anxiety fear of leaving alone, keep going back to my past life that I had with my fiancé that died and I was with since kids, elementary, middle, Highschool college to adult hood. Don't know how to move on with my next life with the person Ive been with for 9 years and had a baby by but I keep going back to my past life tht I previously had a child with him too and she is 14 years old. Other daughter is 5 years old. I need something to help me move forward and stop comparing everything to my past life. I will be happy in the beginning but it gradually leaves and I fall back into this severe depression and mess my life up along with the person I am in the relationship with. I can't stay happy and stay in the present. Please help I'm trying to find a medication to help me stop overthinking everything and live for now.
