how to calm down?

So I might be able to get a doctors appointment maybe some time between this month (may) and June. (I don't know how my mum is gonna do that. Especially since we don't have a family doctor right now. All she said was that she's gonna book one at the front desk for me when she goes to get her blood-test.)

But how to calm down? As to try and manage my symptoms in the meantime? What yoga is there etc? I wanna try some more until I can see a doctor.
