Do sports (at home, if you feel more confortable) but 3x 30min/week. Eat more greens, oilseeds, fresh fruits and food rich in magnesium such as: raw spinach, fish, beans, lentils, avocados, brown rice, bananas, figs and chocolate. If you have a pet, cuddle with it more often and take care of it. It will make you shift your focus from anxiety to something else. Try to catch the sun everyday for 10mins. Check your levels of vit D and B12 (adjust with supplements if needed). Yoga, you can find plenty of stuff online. Mindfulness meditation, it’s not hard, stick to it. When you feel anxiety, let it come, don’t fight against it. Take deep breath (inhale for 6 seconds, hold for 2, exhale for 6. Do it again). Just observe how tense and how bad you feel over nothing. Meditation can help to stand back. Sleep enough (7 to 9hours/night). Quit smoking and avoid drinking alcohol. Smile. Smiling, even for nothing, tricks the mind and releases happy hormones. Learn to manage your anxiety, it’s always going to be there because it’s a normal mechanism of protection but don’t let it rule you anymore. You are not alone.

Need to consult

Madam with regards to limited information what you have provided, you had an anxiety and panic since last 1 year which was well controlled on medicines, which you discontinued gradually. now since a significant life event has occured, you have started re-experiencing anxiety symptoms. So, I will advice you to restart medicines under supervision of Psychiatrist (Preferably offline) and then gradually taper in 4-6 months.
