I very rarely have any anxious thoughts but frequently have anxious feelings. My mind doesn't race or get overwhelmed by anxious thoughts.

My mind could be completely calm but can still just get that grating anxious feeling and pit in my stomach from something that triggers it. Sometimes those feelings can be triggered really easily like just looking at some things can trigger them without any thoughts. 

Even sometimes when I have absolutely no reason to be concerned and nothing will affect me then those anxious feelings can still be triggered.

How are you supposed to deal with or overcome anxious feelings? I find even powering through them when necessary they never really go away completely and that is just too stressful and exhausting to keep up.
