Used cita s for 1 year. Any issues?

Hello all, used cita s 10 for anxiety nd phobia for one year and aplaz 0.5 when stress levels are highe. But I just use aplaz 10 tablets in entire year. Everything was fine till one year, but My Dr said you have continue for another 3 years or stop nd see ho you feel. I stopped nd within 2 months I started experiencing same phobia nd anxiety. It will last for one or two days depending on situations. If I visit dr he will say to continue for another 2 or 3 years cita s. Is this safe? I discontinued, if I start again any issues? Or is there any better to come out. Or suggest me solution or tablet to my issue. I just keep worrying for family issues, now taking tablets for years also troubling me. Please help. Thank q
