Am i having a panic attack. i am having gallbladder surgery tomorrow so the slight nerves might be the problem. really tired then felt like something pushed me down. still lying down and my heart is still racing?

Panic attack: If you can find a quiet place - do so. Breath in slowly & deeply through your nostrils. Fill your lungs with air (but not to the point of discomfort). Hold for a count of five then slowly begin to exhale through an open mouth. Repeat at least 12 times, longer if you need to. If you haven't been assessed for your panic/ anxiety - that would be prudent. Take care.
