I have every sympathy OP, that sounds miserable. It's really common to experience mental health issues in pregnancy - whether it's feeling weirdly disassociated from everything, including your baby... feeling fearful / anxious / angry... or all of the above, and more! You're at the mercy of your emotions: furious one minute, in tears the next. It's exhausting.
The good news is, the more you know and the more support you get, the less helpless and unlike yourself you'll feel. And gradually most women will turn a corner.
Talk to your doctor and don't be fobbed off - insist that it doesn't feel like it's 'just hormones' and you really need help. Prepare by Googling trusted sources (like perinatal anxiety Mind, the NHS website and recommended sources of help on MN), so you can have an informed conversation with the doc.
They should refer you to the perinatal health team. This team "support parents before, during, and after childbirth, focusing on both physical and mental well-being. It includes specialists like perinatal psychiatrists, nurses, midwives, psychologists, and health visitors. They help you manage mood disorders (like perinatal depression) and other challenges, ensuring a healthy transition to parenthood for families."
And in your more settled times, try to explain to your partner, friends and family what you're going through. I'd apologise (but that's up to you!) and ask for their patience while you're getting help.
