Hi there BPSquared
It is good to have you on this forum.
I just wanted to say that you are not alone in how you are feeling and that I could have been reading about
my hubbie and his feelings of late.
"The suicidal stuff is gone, but now I have no interest in anything: work, hobbies, sex, vacations, or leaving the house.
I am in a buying mode (my normal UP behavior) but I regard the purchases as just something else I do that I don't really care about
. It's just something to do"
These words really resonated with me. We have been together for 20 years, but he has only been diagnosed for the past 2 and in these couple of years has tried a 'cocktail' of different meds prescribed by his psych and is currently taking Lexapro (last 2 months, prior to this he was on Effefor XR whose effect had gradually 'worn off). It is interesting to hear that the 'last time you were really down/suicidal thoughts etc' and I am wondering whether this is why you are feelling like this now. My hubbie has always had bad periods of depression and big highs but his last one was the longest and for the past 7 months I imagine has felt similar to you.
So I wonder know whether this very very long low period has resulted in his current feelings. I am not sure how long you felt 'bad' this time but I would be interested to know. Also taking the Lexapro which was new to him, I wonder what impact this had had. Like you he is not immediately suicidal but totally lacking in any interest in the future, hobbies, life in general, in fact his usual words to me on a daily basis is that he doesn't really know what he is doing in life anymore and why he is here. He does have a tendency to go into 'buying' mode like you and this has always made him feel better and he has bought certain things in the past few weeks in an attempt to cheer himself up BUT on this occasion for the first time ever in our time together they have not made any difference to his mood at all which has been a strange one for us as usually these things do cheer you up for a few days at least
Anyway, I suppose I don't have a magical answer for you, just that you are not the only one and it could be that you are in a 'mixed state', it could be the meds, could be the end of the deep low or a mixture of all of them. In anyway I would say that 6 months is a long time to go between doc visits so I would definately be going back and telling them how you feel and maybe getting more regular visits (just my opinion). My hubbie visits his psych once every 5 weeks approx. and to be honest it is not enough.
Like you say keep trying to channel those compulsive feelings into doing some practical and useful.
Please keep posting and let us know how you get on.
