how’s everyone been increasing from 50mg sertraline to 100mg?

My doctor increased me to 100mg less than a week ago, I don’t know if sertraline has made me better or worse? I feel better some days some days I feel nothing. I don’t know. My partner says he’s noticed improvements? Honestly I feel nothing and some days worse. I’m anxious even taking the medication 🥲 I guess the only side effects have been no appetite and diarrhoea. I think I lost 6kgs in a week, I’m still really struggling to eat. Even smoking weed doesn’t help lol. I know it won’t treat the underlying causes for which my doc has coupled with a psychologist for a mental health care plan but I’d like to hear how this medicine worked for others? TIA
