Deficiency on a few vitamins. What should I do?

Ive been low on copper for 4 yrs and take 2mg everyday for ages. I tried upping the dose to 4mg before but felt a bit sick actually.

My Vit D levels are just below the 30 normal range. I tried taking Vit D but have effects from this. A few days ago I had some really good news from back home and was in a fine mood all day. At 6pm I took a vit d after a meal and at 8pm I was sitting at my computer and for some reason started feeling agitated/ angry. It had to have been that vitamin pill. Its not the first time. I dont like exposing myself out in the sun due to melanoma risks and I dont like the red burnt face look.

I also have zinc deficiency and started taking a brand of zinc around 25mg every second or 3rd day. I took one last night after dinner. Woke up this morning with pain in my chest and dull pain in my jaw. So many the dose is too high. Also I found that a few hours after taking zinc I kind of have brain fog and when eating I accidently bite my lip

Im wondering if I should go cold turkey on all vitamins and see what happens. Im middle aged and my hair seems to be thinning anyways which is normal. Maybe most people are deficient in some things like this but dont know and do nothing and just get on with life. Should I just do the same?

6 months ago at Bumrungrad they found the above deficiencies and sold me some expensive vitamins. They said I probably have malabsorption issues and gave me a digestive enzime which I take everyday.

Dont know if I should bother going to see an Endocryne dr instead? Can anyone recommend a specialist at any hospital in bkk?

thanks
