Thanks Mark for the reassuring words. Yes I am aware I can be anxious and stressed and that I haven't really nobody to help me relax.
And just recently I think I realized that in my case "stress" is not being too tired of job/life but a combination of many other psychological factors.

At the moment my job is the only real thing in life that keeps me motivated and I can't afford to under perform in it.

It's hard for me to acknowledge that symptoms that I experience in a objective way are originating from stress. Especially that weird feeling on the tongue that really I can't explain.

I will have a look at your recommendation about supplements and try to take it easier. About me currently I am in Switzerland and I am originally from Italy.

At least believing in God helps me feel not so alone and I can hope that things will get better.
