Depression

Anyone else going thru bouts of depression? I never really thought of myself as depressed before although some people have asked if I’d seen someone for it. I’ve seen counselors/therapists over the years for family issues but not recently. But now that I’m pregnant I feel depressed & bipolar. I never want to be around other people & I get overwhelmed VERY easily. My SO & I used to go to bars & I smoked but now I want to be as far away as possible from bars. I feel so alone & don’t know what to do & I’m terrified these emotions are going to be harmful to my baby 😔 I’m 26 weeks today.
