Feel really low and suicide plan, on meds for depression. is it worth seeing a doc? what can they do?

Take action now: Continued depression with suicidal thoughts and a plan is a terrible place to be, but you are not alone. Seeking help by being as honest as you have been here can help with identifying actions steps and medication options. There are a large number of medicines that can help and everyone responds differently. My experience: those he keep trying all options eventually find one that works.
