Hii... the symptoms you describe—night-time chest sensations, body jerks while falling asleep, these can occur in Depression and Anxiety Disorders, especially during periods of high stress or in the initial phase of starting antidepressants like Paroxetine.
These are usually not dangerous, but can feel very distressing.
Next Steps
Continue medications as prescribed and follow up with your psychiatrist. Dose adjustment or short-term support for anxiety/sleep may be required. Also, rule out physical causes if symptoms persist or worsen.
Health Tips
Practice slow breathing exercises during episodes (inhale 4 sec, exhale 6 sec)
Maintain regular sleep schedule
Avoid caffeine, especially in evening/night
Try relaxation techniques before sleep (music, meditation)
Reassure yourself that these episodes are temporary and manageable
