Help ! Opinions please

Okay ladies so I know I’m not the only one who deals with depression. I have fought this almost my whole life plus add anxiety and possibly bi popular issue . Through out my years my mental illnesses hasn’t gotten better but I mange. I’ve even tried self harm ,self medicating etc . It was never easy . Before I found I was pregnant I was planning on seeing some doctors to help me but that changed in a test . I was scared and nervous bc it’s not not has it been easy dealing with my stress ,my husband ,my mental illness while being pregnant. My husband brought up maybe I should get my tubes tied after delivery,but I’m not sure . This is my first pregnancy and sort of a miracle that this is happening . With everything going on and my mental state tube tie would be my best option bc I don’t what this pregnancy will bring or how it will affect me after she’s born ...I don’t know . What I do know is that I’ve always wanted a child and I always asked god if he could bless me with just 1 ,I would be so happy . I have a lot of thinking to do and just wanted some opinions on should I get my tubes tied or just wait ?! I’m stuck on this and I still have 4 months or so to decide but it’s hard . So please if you can weigh in on this alittle I’d appreciate it . Thank you
