I am a 14 (a week from now i will be 15) and for the last 2 years i felt like i havent been able to breathe properly sometimes it gets so bad to the point of where i start crying and thinking i will die i have been to the hospital around 3-4 times for it but have never been diagnosed with anything i am a little overweight (im 76kg) i was on anxiety medication (fluoxetine) it helped for about a year and then recently it has started happening again and i switched to a different one (sertraline) and it hasnt been helping and at night when i try to go to bed sometimes i start to feel it happen again but the second insit up and chill for a minute it goes away and i really hate this feeling its stopped me from doing sports (hence the weight gain) and idk i just feel like i need to yawn to breathe and take really deep breathes to feel like im breathing bcuz without it it doesnt feel like im getting enough oxygen
