is it normal to only get anxiety mostly at night? 

i’ve been such a worry bug lately. and i noticed that during night time when i lay down, or just in general towards the night time, i start to have shortness of breath. so of course, i get in my head and start becoming nervous and shaky. 

i googled some thangs. 
and congestive heart failure comes up. and i’m trying my hardest not to diagnose myself but i’m not sure if it’s anxiety i’m having every night or an actual heart problem. 

i’m planning to see my doctor in the next few days
