Its great to see you reaching out on the beyondblue forum. There is great support here and many people who are in a similar situation as yourself. Caring for a loved one is rewarding but is not without its challenges. I have seen carer burnout or compassion fatigue in both colleagues and friends. It is really great that you are reaching out to get some support for your own needs.
I realise that living in a country town can be tough to get support so will offer you a few suggestions on getting through the next few weeks before seeing your GP.
There is a free program that operates in some parts of Australia called NewAccess. It’s a program developed by beyondblue. It is worth looking to see if it operates in your area. Some of the NewAccess programs can be done over the phone and mostly focus on people who are experiencing depression and/or anxiety. You don’t require a GP referral. The link is below for you to have a look at.
Another option to use before you go to your GP is to use the beyondblue support line and speak to someone on the phone to get support through this really difficult time. You can ring the free support service anytime on 1300 22 4636. This can be really helpful to get you through the next few weeks.
Finally, I would suggest you ring your GP and ask for an earlier appointment based on the information you have provided. You mentioned you have increased your medication however I advise that you do this under the supervision of your prescribing Doctor. This way they can assure you are physically well and able to take a higher level of medication. I realise it is difficult but perhaps you could explain to the receptionists that you need an earlier appointment or ask for a call back from your GP. Getting into to your GP sooner would be the safest way forward in getting the right treatment quickly.
You might also ask one of your family members who live to come and support you for a some days to get a break. Do any of them know about your depression or is there any of them that you trust to talk with them about how it is impacting you?
Working both full time and looking after your mum is a big load for anyone but when you are under the cloud of depression, it can feel even heavier.
Be kind to yourself and use as much support as you can to get you through this difficult period. And keep posting around the forum - you are not alone.
Wishing you the best possible outcome,
