Hello and welcome to Helathcaremagic, Some anti depressants can cause withdrawal symptoms upon abrupt stoppage. Especially the short acting drugs, which require multiple dosings. (Unfortunately your query lack the name of the anti depressant). These withdrawal symptoms can be both physical and psychological. But there is no need to be worried as these symptoms are mild and can be easily treated. My advice to you would be to follow your doctors advice in future and slowly withdraw medicines under supervision. Hope I have addressed your concern. Do feel free to ask further and I shall be happy to help.
