I dont know if this is called shortness of breath or whatever but here it goes so when ever my heart starts beating heavy and i try and breathe for some oxygen... no matter how deep i breathe it feels like i cant fill my lungs if that makes sense? this happened a lot today when im trying to catch my breath but my lungs just dont want to fill with oxygen.. i dont know if it does or not but it just doesnt feel like it does. does this happen to anyone else? btw, i went doctors about it he said i was fine... but im phucking not and it affects me. also when im havin a warm shower i cant breathe deep as well... well it feels like i cant.. anyone else having these troubles brahs? EDIT: I take mesomorph.. thats all. I used to take protein but i stopped coz im bulking heavy on natural ****.
