When I was about 11 or 12 years old, I had this blinking tic where I would just blink uncontrollably until it went away on its own, now, at 18, that same tic has manifested again. Also, about a year ago I would have episodes where I had trouble breathing and my heart rate was accelerated, but I would go to the nurse and they would take my pulse and everything and couldn’t find anything wrong. I assumed these were panic attacks but it wasn’t in reaction to stress or anything, it would just randomly happen. This lasted for about a week until it went away. Recently, however, I have had these episodes when using cannabis, even though I’ve been using it regularly for about a year without that effect. I’m not really stressed or anything and I even meditate to manage my stress. I’m thinking it could be all these transitions I’m making since I just graduated High School. Does anyone have any ideas as to what it could be? Maybe I do have anxiety, I don’t know.
