My anxiety mostly comes in the form of more physical symptoms. Mostly heart palpitations/ nausea/ hyperventilation. I could say before that my anxiety was tolerable. But the past couple weeks I'm feeling the symptoms all the time. The whole day. I've never experienced this before and it's really unpleasant. I've started to exercise, eat breakfast and just try to be more present when it comes to doing any activities. I lost my gran about 5 months ago and I'm not fully sure if it's the symptoms of grieving getting in the way (it's gotten worse since her loss but hasn't been this bad). 

What do I do about this? Please help.
