Am I having stroke/brain haemorrhage.

I am having weakness in both arms especially right one since yesterday night! I also feel fatigue n tired! My vision also is blurry... morning I went to eye doctor- complete eye exam done n he said nothin except mild increase in right eye number! I am very scared of having stroke though I am 21 and no family history of stroke I am not sure if I really have a weakness or it's just anxiety because I am able to use right arm easily n lift things up.... I have done that FAST test of stroke nearly 15 times since afternoon.... I was admitted to ER in July for right arm weakness n dizzy spells... CT done that time was fine... I had b12 deficiency but numbers were normal in November I will see neuro tomorrow but want some assurance
