Pet Scan Results - Looking for layman answers.

Received results from my PET scan today and a call from my doctor. I have tried to research the following with Dr. Google, but he isn't helping me. I am totally stressed about this and don't have an appointment until the middle of May. My anxiety and depression are spiraling out of control and I would just like some answers that I can understand and get me through to my appointment. How serious is the following diagnosis? Did I catch it early? I have been doing the annual CT scans for years and two nodules showed up, but never grew. They were the Lower Left Lobe and Right Upper Lobe. The lymph node had not been diagnosed before. I stopped smoking in Dec. 2023 and now they are growing (I'm sure it's a coincidence), but still.... any information would be greatly appreciated.

Lung nodules: 1.1 x 0.8 cm nodule in the superior segment of the left lower lobe is the recent CT and demonstrates mild metabolic activity with a max SUV of 2.1.

Adrenals: Low-density nodular thickening of the left adrenal gland most in keeping with an adenoma

Mediastinal: 1.1 cm short axis left paratracheal/AP window lymph node demonstrates significant hypermetabolism with a max SUV of 19.7.

IMPRESSION:
1.1 cm nodule in the superior segment of the left lower lobe demonstrates mild hypermetabolism suspicious for a primary lung malignancy. There is an enlarged markedly hypermetabolic left AP
window lymph node suspicious for nodal metastasis. No evidence of distant metastatic disease.
