Pregnancy hormones/depression and anxiety

Almost 12 weeks pregnant and having bad anxiety attacks and general mood swings. Feel okay one day or several days at a time, even happy. Then suddenly will feel exhausted and with that comes feelings of guilt, depression, shame dark clouds over me... increased anxiety about the future, overall dissatisfaction with current situation and worried it won’t resolve in time for baby.... have a hard time grasping the concept that every feeling and moment is temporary and the future is bright.. is this normal? Can any future moms relate?

I am feeling the emotions I’ve been experiencing are so intense i May need to discuss with doctor and/or start seeing a therapist. It feels like very severe PMS/depression. Scared to go through this for several more months. Anyone else experience this??
