laurar,
I am not familiar with dosing guideline for 5HTP. I am sorry to hear you are going through a tough time but suspect some of it is recent major changes. For many of us, disruption to familiar routine sparks anything from mild anxiety to extreme terror.
Try to take it one day at a time and yes, I do believe you will get through this is you allow yourself to feel and not get caught up in the anxiety. Be good to yourself and congratulate yourself on how far you have come already.
Gentle Hugs,
Kitt
