Hi been on sertraline 200 mg for about 6 years it's helped  smooth the bumps on the road.  Was able to get back into work. Usually go through dips in mood but can manage. But in the last three three months I have been struggling to cope lots of stress in my life.  Tried propranolol strangely made me more depressed.  Thinking about switching meds but scared of withdrawals. Any thoughts or advice would be appreciated.
