Sertaline/Zoloft 5weeks on 25mg. Will it ever work?

Hi everyone. Iam on 25mg Sertaline for 5 weeks now. I didn't want to move up to 50mg and wanted to see if this dosage enough for me. Im still hoping, but Im afraid it wont ever work for me on any dosage. I have had side effects, some better days as well but for about two weeks now its just the same as it was, no improvement.

I read that many ppl stays and feels good on 25mg. Who does, can you tell when did it start to work?

Should I wait more or up my dosage or just give up?

Thanks for any advise.
