Uy, mama, ang daming pinagdadaan mo, physically at emotionally, at hindi ka naman naririnig. That's heartbreaking, talaga.
Listen, what you're feeling (the back pain, stomach pain, dizziness, headaches, anxiety, depression), lahat yan deserve ng proper medical attention from your OB or doctor, especially with your anxiety and depression getting worse. Please don't wait on this, see your doctor soon, ha? You need real support, not dismissal.
But beyond that, the hurt you're carrying from your partner, ang loneliness ng pakiramdam na wala kang partner sa pinakamahirap na panahon mo, especially after everything you've sacrificed, that's real, and you deserve to feel heard. A few of my mum friends have been through similar, at nagsabi sila na sometimes couples counseling or even just a calm conversation with someone you trust (like your doctor, or a trusted elder) helped the partner understand na ang pregnancy complications at emotional struggles ay not "excuses", they're real.
You're carrying so much alone, mama. After your check-up with your doctor, maybe think about talking to someone, a counselor or a trusted friend, about what you need from your marriage right now, ha? You're not alone in this.
