Shaky fingers and anxiety. Today.

Feeling jittery most of the time. My fingers trembles a little. Left hand fingers trembles more than right hand. Mostly when using touch devices like smartphones, while typing I see trembling. I have to focus and type. Trembling is minimum in morning immediately when I wake up but after 30-60mins I feel it again. While on rest palm n finger trembles are not present but while doing small actions like holding small needles,. typing it can be seen. Trembling increases substantially when I am a bit excited or anxious. Symptoms has been since a year. I had done all basic test like lipid profile, thoiroid test, b12 deficiency test, blood sugar test but all are negative. Sometimes when anxious feel my knees joints are trembling thought not visible. pls suggest me what shud be my action. This physical symptoms are making me feel weak in many real life social situations. Under influence of alcohol symptoms reduces substantially. My BP records to 140/100 n pulse 97 as measured today.
