Hi @Meecie,
A warm welcome to the forums and sorry for the delay in someone replying to your post from the other night. There is often alot of traffic on these forums and even though it is constantly moderated, sometimes a newbie slips past us for a while.
Reading through your post, I can feel your frustration at your lack on progress on the medication, and constantly feeling low and anxious. Many people here will very much relate to that ongoing cycle of their illness, and having to struggle through the "bad" patches.
Has your psychiatrist been offering any psychotherapy, suggested any self management for low mood and anxiety, or support programs? Sometimes people get a mental health plan from their GP in order to see a counsellor for the practical and self care aspects of treatment.
Medication is not effective for everyone and can only be considered one part of a complete recovery plan for bipolar disorder. Have a read in some of the other threads to see what others have found to help them get through the tough weeks. You will get a lot of support and understanding here.
Hope to chat with you again.
kind regards,
Frog
