I am suffering from anxiety, depression and ocd i have been taking sertaline in the past bit i since i dont want to relay on the medication i stopped taking it. now i felt more anxious and depression ?

That's what happens: That's because she who does not have serotonin in adequate amounts in proper brain locations will get symptoms if she stops taking medication. Hopefully (after she gets rid of most of her symptoms by using her medication) she will be able to wean down her meds during the good times of the year (low stress times). She can work with her primary care or psychiatry doctor on this. No need to suffer.
