What are good uplifting bible verses for depression?

Im 6 1/2 months pregnant with my third child. In this pregnancy I've been in a total roller coaster spiritually and I believe partially its hormonal. In the beginning I was very into my christian lifestyle. I was very involved in church, was attending all services, activities, fundraisers, bible studies just everything! I was happy and positive and had this sense of who I was to serve the Lord. All of a sudden into my fourth month I've been going into a downward spiral of doubt and insecurity. I am deeply depressed never once have i blamed God but instead I blame myself with continuous put downs. I have even started to become suicidal buts embarrassing to find help in my christian community. ...What bible verses can help me to uplift my spirit and bring me back into the right path?
