Hi Private It sounds like you are having a rough time, even though feeling better in some ways
The interaction of depression and anxiety is very complicated. My anxiety was more of the worrying/ruminating/looking on the dark side type of anxiety and very tied in with my depression, so that the ads help both together. It sounds like your anxiety is more "physical" and less associated with thoughts, do you think this is the case?
I think with the ads it is very much a matter of trial and error. I don't think the medical profession really know why some meds work for some people and not others. One thing I would mention is that my experience with sertraline is that there is a tricky balance to be struck on the dose. Sometimes I. go into a decline and have to increase my dose (with Dr's agreement). I then improve but after a while I find I get very agitated - ants in my pants - and I have to decrease my dose again. I've been round this cycle a few times now and because I have, I can recognise the signs of when I need to increase or decrease my meds but it is tricky to get it right.
You were on the lower dose for 3 weeks, I think, before you increased. One thing to consider and discuss with dr (and I know this sounds counterintuitive as you are still not feeling totally better) is whether to try reducing to 50mg again. Unfortunately I think trial and error is the only way to find out what works for you.
I only take the sertraline for my mental health, but I have heard other people talk of taking a combination of meds. Perhaps that is something else to discuss with your dr, whether you could keep on the sertraline, which does seem to be helping the depression, but try something in addition for your anxiety.
Can you identify whether your anxiety symptoms have increased in the last few weeks?
I really understand how upsetting it is when you just want to get back to normal and enjoy your life and you are still feeling intermittently awful. It is still quite early days on the ads, so it's difficult to know whether you should just persevere with your current prescription or ask to try something extra or change dose. I would say the main issue is whether things are improving, even if only slowly, or whether they are getting worse or static. Can you try to identify whether things are improving or not?
Hope you get a good night's sleep.
