Your low platelet count could be due to drug side effects. There are so many reasons for low serotonin but you have already listed one reason - vitamin D deficiency. Find the underlying cause of serotonin deficiency and you no longer have to suffer the possible side effects of the drugs.
My main reason for severe depression was due to severe vitamin B12 deficiency (just to add vitamin B12 and folate deficiency are causes of low platelet count too). For my mother, severe depression was due to severe stomach acid deficiency (to produce adequate levels of stomach acid there must be sufficient chloride, sodium, zinc, vitamin B1, vitamin B6) and another time due to a low fat diet. I adore my saturated fat and cholesterol rich foods. My cholesterol, HDL, LDL, triglycerides are all in optimal range. That is my two cents. A few excerpts below you can read through....
"In Framingham, Mass., the more saturated fat one ate, the more cholesterol one ate, the more calories one ate, the lower the person's serum cholesterol. The opposite of what… Keys et al would predict…We found that the people who ate the most cholesterol, ate the most saturated fat, ate the most calories, weighed the least and were the most physically active."
"When you replace saturated fat with a higher carbohydrate intake, particularly refined carbohydrate, you exacerbate insulin resistance and obesity, increase triglycerides and small LDL particles, and reduce beneficial HDL cholesterol."

"The following factors can cause low serotonin levels:
Artificial sweeteners (aspartame)
Dietary deficiencies of nutrient co-factors
Ecstasy, Diet Pills, and certain medications
Hormone Imbalances (thyroid, adrenal, estrogen)
Lack of exercise
Lack of sunlight [lack of vitamin D]
Problems converting tryptophan to Serotonin
Problems with Digestion
Stress and Anger
High Cortisol Levels
Low Serotonin Symptoms:
Low serotonin levels are often attributed to anxiety, depression, panic attacks, insomnia, obesity, fibromyalgia, eating disorders, chronic pain, migraines, and alcohol abuse.
Negative thoughts, low self-esteem, obsessive thoughts and behaviors, PMS, and Irritable Bowel Syndrome are also symptoms of low serotonin."
One thing I am not is depressed, thank the Gods. Yes, it has been a struggle but that is what life brings and one has to deal with them and look at life in the joy that it brings.
As far as deficiencies caused for me - meds, smoking and getting my body healthy again are the essential factors I need to get in order.
The Von WilleBrand Blood test results should be completed today and I hopefully have the results by tomorrow the latest.
I just want to know what to do to rectify the damage and wake up feeling like I can do things and be very active opposed to feeling so fatigued. My mental state is in a very good place so there I know I can say cool, 'for a change my mind is ok'.
Thanks for all the information that you shared. It was interesting to read.
I just want to play hockey again.
