Advice needed

Pleaseee help I need advice. So I’ve had fainting spells starting like 5-6 weeks ago and I went to the doctor and they said I would have to get a bunch of labs run on me which was scary but fine. The labs come back and they think it could be a thyroid issue but they still need to run more tests. An ultrasound, Ct scan, and 8 mill blood draws later we go to a specialist and she said it might be lymphoma a type of blood cancer. Tmr morning I get a biopsy helppp I get anesthesia but they still have to poke needles in my lymph nodes. Also I have my best friends bday party the day after and I would hate to make the whole thing about me if it does turn out to be lymphoma. Pls help
