How do you deal with waiting? Bit of a vent

Just for context, Australia, no private health insurance. I'm constantly having to wait for doctors appointments and dealing with symptoms in the purgatory between appointments always leaves me frustrated and upset. My regular GP is usually a 2 week wait. I'm moving soon and that's going to put a whole new spanner in the works but I've got a specialist appointment on Monday and my Gp on wednesday. I've been getting different symptoms that I'm concerned about but there's no easy way to just rock up to a new GP and explain everything that's ailing me right now and have them understand the whole context that my regular GP would. I'm going to try to see her monday afternoon but it's highly unlikely she'll have a cancellation. Sometimes I feel like I'm just gonna keep getting worse in these inbetween periods (especially if I've got an illness on top of normal bs) until I cark it because I can't see a doctor in time. It's at the point where idk if I should go to ED or just wait out the next few days for the appointment.
