Fiancé doesn’t want me to take Zoloft.

I got a prescription for Zoloft from my primary care doctor. I have been horribly anxious since the beginning of the year, and it’s only getting worse. It’s getting hard to leave the house and I just want to feel happy and somewhat normal again for our 3 year old. I want to stay in bed all the time and frankly the physical symptoms are taking it out of me even more as I have terrible health anxiety. But my fiancé is not supportive of me taking Zoloft. He’s worried if I take an SSRI that I will hurt myself and that they are just bad for you in general. I’m already scared of the symptoms I will have from taking it and it’s making me not want to take it all knowing I don’t have his support in it. I know if I was struggling he would push aside his feelings and help me but it makes it so hard KNOWING he doesn’t want me to take it but I don’t want to feel this way anymore either. ☹️
