Just wondering what I could do or test for physically. I just wonder if all the blood pressure issues and being laid-off for five months finally took ita toll. Could using anti-depressants cause depression? Didn't have bad thoughts until trying lexapro and zoloft. took them for only 11 days. My pschatrist and regular doctor do not think my blood pressure medicine would do it. Worrying about my healt to much would they say. Been on omega-3 and B-6 for 4 days and have felt better. My blod pressure med is Benicar. It is a new one. Took it for over a month before any of the depression symptoms. Didn't have bad thoughts and suicidal feelings untill after trying lexapro and zoloft for anxiety.
