Anxiety and depression

I’ve been struggling with my anxiety and depression for a bit now due to some fairly recent events that happened between my fiancé and I. I don’t know how to deal with these feelings as hey come and go in immense waves. Counseling is currently off the table as we are having money issues right now and I really do not want to be thrown into a random medication again by my PCP because I’m almost 15 weeks pregnant. Anyone have any suggestions on how to calm anxiety when it comes? Or how to uproot yourself from a depressive rut? We have a 2 and 3 year old that are counting on me to stay positive and be super mom and I’m just feeling so drained 😞
