I would strongly recommend psychotherapy over any psych med.
I can relate a little to what you're going through. I have put on some weight recently due to stress and emotional eating. My wardrobe is somewhat limited and I barely fit my clothes anymore. I am afraid that if I put on weight this week I won't fit into anything next week.
I have a copy of Dr Gould's book on emotional eating and are slowly working through some of the exercises. I have noticed that the worse I feel the more I eat the worse I feel and the less active I become. And the cycle starts again.
I can't even comprehend one whole year, let alone 53 of them. I am younger but feel ancient. Very ancient.
I was discussing treatment with my doctor yesterday and again cost came up.
He said that if I had a heart issue or needed a liver transplant that due to my age I would be a priority. Because I have been diagnosed with a mental illness, and a difficult one, I am barely given any consideration at all. None by the mhs.
Mental illness has exacted a huge personal cost from me. My doctor has said that it is a loss to both me and society. I think it's devastating that something can rob you of so much.
The moral of the story? Don't trust psychiatrists. Most are useless. Use how you're feeling as a guide. Strive to make your own life work for you.
From my perspective, that of a disgruntled and disillusioned layperson, I think you're taking way too many meds. I think you should access psychotherapy and start working through your underlying issues, the ones making and maintaining the low mood.
You may not become suicidal again so it may not be an issue. If you are concerned then make sure you come off under medical supervision and with the support of your husband.
I have learnt that suicide is often a way of communicating distress. If you are able to identify the feelings and work through them you are much less likely to become as over-whelmed.
I should apologize. There are some good doctors out there. I just become frustrated when they perceive we are well when we are clearly struggling and have issues.
Some of my own frustration has come through in my post so leave that and take anything you may find helpful.
same advice I gave you a few moments ago...you and your doctor have to decide together what is best.
