Depression Triggers

This depressive episode has me dealing with some depression symptoms that are not normal for me. My symptoms include weight gain, hopelessness, inability to feel pleasure, lack of interest, sadness, extreme fatigue, sleeping more than normal, excessive hunger, restlessness, and suicidal ideations. I push myself to get through this every day. I make myself get out of the house because I know it’s good for me. Just because it’s good for me doesn’t mean it’s easy to do.

I’m trying to figure out why this depressive episode is even happening. Normally, I can pinpoint the reason or trigger for an episode, either depressive or manic. Some of the reasons are medication induced, situational, or emotional. The problem is that I can’t find the reason for this depressive episode. I’m wondering if it’s possible that my recent ECT treatment could have caused this depression. I had already started to feel slightly depressed when I had the treatment, but I have felt so much worse ever since I woke up from it. It feels like ECT was a jumpstart into depression.

Does it even really matter what the cause is for any episode? I suppose the reason to know what triggered an episode is to help for the future. If you know what caused a depressive episode, then you can avoid that trigger in the future. I’ve been doing ECT treatment for over a year, and this is the first time I’m having problems like this. It may not be a trigger for me, but it may have been the thing that pushed me over the edge. Other things I’ve been experiencing that can cause depression are poor sleep habits, poor diet, weight gain, other health problems, and feeling home sick. I wonder, with this such as weight gain and poor diet, which was first. Did they occur first as a symptom of bipolar depression or were they triggers for the bipolar depression?
