My Rheumatologist says I have Fibro not Lupus

HI, I stareted to feel really sick about 2 months ago. Lost 6 lbs extreme fatigue, weakness, bones ache etc..my GP did an ANA and it came back 1:320
I went to a rheumatologist and he ran all the ususal antibody tests and the only thing that came back was anticardiolipin and it was 10. Which is considered interdeterimint and therefore he said all I have is Fibro and to exercise. I feel so sick and my joints ache and im so tired all the time. Do I really only have fibro, what should I do. I also have hashimoto's so he said the ANA was from that, nothing else. These docitrs keep telling me I am depresessed as well, its very frustrating. Also I get daily migraines and terrible memory problems.
