I'm so scared I've done damage to my baby.....
I can't see how.
Will I get withdrawals from 25 mg of Zoloft after only 9 days?
No. Dependence only becomes an issue after a month or two
Is my sleep permanently ruined?
Not because of the Zoloft, however, there is a strong psychological component to sleep so it is possible to talk yourself into insomnia.
I feel like I should have started therapy first before even trying the Zoloft
Therapy is a great alternative to meds, but it usually takes much longer for good results. Your baby may have been born before you got the anxiety under control.
I'm upset the dr put my on 50 mg the first four days
While not ideal, I don't think this has caused the ongoing insomnia
I feel like I will never be the same again
Sure you will. One bad night indicates nothing.
I don't know what to do
IMHO, you should continue with both the Zoloft and trazodone, though you may need a higher dose of the latter. I suspect that much of last night had more to do with panic when the trazodone didn't work as quickly and/or effectively as you remember it than either it or Zoloft per se.
