Hello and welcome
I'm sorry to hear you have not been feeling well for so long.
It sounds as if getting that doctor situation sorted seems a priority right now.
Once you are able to go to the doctor it might be an idea to get your ANA retested (I presume it already was during previous investigations) and see whether that comes back positive or not. For most SLE sufferers it will (though not all). There are then further tests to be done to see whether it is SLE or not as well as the clinical symptoms which are esential in diagnosis.
The problem with lupus is that it is a very complex disease and also a great imitator, so not at all easy to diagnose or to get diagnosis. It is important not to go in to a doctor "sure" that you have SLE or indeed to convince yourself of that. The complexity means that it could be so many things. Docs don't take well to patients coming in and saying they think they have so and so.
I think that asking the GP if he/she thinks that anything autoimmune "might" be going on and asking for a referral to a rheumy would be a good starting point (or maybe even a dermy if your skin problems are rashes - a skin biopsy might be a helpful diagnostic option in your case - I'm not sure from your description, you'd obviously need to run that by the doc).
It is best to try and see a doctor who has experience in autoimmune diseases. Not all rheumies do. There is a find a doctor section here on the boards where you can ask for recommendations from our members in Canada.
It might also be worth taking time to look up the diagnostic criteria here in the "Not yet diagnosed" section to see whether anything fits. Sometimes we have so many weird symptoms that seemingly have no link that it's not easy to tell what's what.
Keep us posted on how you do and I hope you get that doctor situation sorted fast.
