It took me a couple of years but you know how I fought it? With prayer. I know that sounds cheesy, but look. Who's the one person always sure to be in your corner. Who's "got your back" so to speak.
Anxiety and depression run in my family and I was determined not to let doctors tell me I just need to take a pill. I still battle it from time to time. Have to just get away from a crowded room immediately some times.
But now i'm 7 weeks pregnant and i'm fighting the battle for my baby. I won't let anxiety win.
Keep strong. You won't always be perfect, but your baby will appreciate your calm.
