Physical Symptoms

Is it normal to experience physical symptoms for months especially after trying out energy work? I’ve been suddenly riddled with anxiety (purely physical, no previous history whatsoever), headaches/head pressure, heart palpitations, insomnia, blurred vision, brain fog, significant weight loss, and a few others. All of my medical tests have returned normal! I feel like I am going crazy. The worst is the physical anxiety symptoms, particularly the ‘stomach drop’ sensations I’ve been having. It’s very gut based. Like I said, no previous history of mental health issues whatsoever. I normally practice yoga and mediation. Has anyone struggled with physical symptoms while delving deeper into spirituality or trying energy work?
