Youre all so friendly thank you

I tried meditating once but I was like "so I meditated now what?" I guess thats why it didnt work.
Thinking the worse scenarios and if it wont happen its kinda relief or tiring or both ? Because brain is like a worse scenario machine you think even the impossible thing.
I went to see a doctor today because I sigh too much. She said I have one blood test coming up and it probably will come out normal. and said i probably have anxiety and I can see a psychiatrist. My brother says I dont have anxiety , its just a habit (sighing) but we'll see
