It may, especially if you have been on bromide medications;

dark thoughts (e.g., there is no reason to live)

I assume you take iodine, how much?
Consider taking lithium (orotate or similar)and / or St. Johns worth;

A commercially available supplement called Amoryn has recently proven to help patients suffering from depression, anxiety, and OCD [69,70]. The main ingredient in Amoryn, St. John's wort, has been shown to help OCD patients better deal with their recurring thoughts and compulsions. Two double-blind, placebo-controlled studies were recently performed that compared the affects of a 900 mg daily dose of St. John's wort extract to 20 mg daily doses of Paroxetine (Paxil) or Fluoxetine; which are both SSRIs used to treat OCD. In comparison to patients taking Paxil, those who took the St. John's wort supplement showed a 57% decrease in OCD symptoms and were 47% less likely to exhibit side effects [69]. In comparison to patients taking Fluoxetine, consumption of the St. John's wort extract reduced 48% of OCD patient's symptoms [70]. These results clearly depict how the use nutritional supplements can be effective treatments for mental disorders.

I recognise the dark thoughts, but I sometimes also have anxiety.

In his book Healing with Nutrition, Dr Wright recommends B3 in the form of niacinamide and tryptophan for Depression and anxiety. I use the niacinamide, works very well for me, calms me right down.

Also, salt pushes help, because they get the bromide out of your system. I always get happier and more energetic after doing a salt push.
