Need some advice
From 2022 I am having episodes of higher anxiety, low mood, fatigue, joint pains that lasts for 4- 10 days followed by 4-10 days of feeling better. The shifts from low days to better days take 1 or 2 days.
At that time I felt the episode more like an anxious state. But I can't find any triggers for my anxiety. The episodes started with lower energy , low mood, brain fog then I feel scared or too heavy to do all activities.
Took some meds for the same. Later due to this episodic nature and feeling of higher energy despite less sleep for 2 days made them to diagnose as rapid cycling bipolar 2. Took meds for the same, meds helped me for the first 2 or 3 weeks then the episodes started to appear again. Tried various mood stabilizers and antidepressants for more than one year. Then I changed my doctor and they diagnosed me as dysthymia and took meds for the same for 1.5 years, same result symptoms improves on change in medication for the first 2 or 3 weeks the. The episode comes again.
Now I stopped all my meds after consulting another psychiatrist for proper taper but he made me stop cold turkey. Later reintroduced some meds on my concern.
Now it's been 3 months I am fully off meds. Still having these episodes sometimes intense sometimes milder.
I checked my homocysteine level which is 21 normal(3-15) which neither me or my GP don't know would cause these symptoms.Heard it's due to vit b deficiency which can cause some of the symptoms.
And these episodic symptoms started after covid.
Now I am confused whether to give psychiatric meds another try or have to investigate whether there is any other underlying cause.
TL;DR- having very brief episodic symptoms which are firstly treated as rapid cycling bipolar 2 then dysthymia but not having any improvements and I am not confident with the diagnosis.Now stopped all meds and still having episodes. And also having a homocysteine level of 21 which I don't know would cause similar symptoms.
