Blepharoplasty in October, worried about flying back alone

I booked a consultation for Blepharoplasty and I am thinking to travel in October because work is quiet then. I would go alone from Manchester, stay 4 nights, and fly back on day 5 if the clinic says it is okay. My worry is not the operation itself exactly, more the small practical things. Will I be able to manage airport, passport control, carrying a small suitcase, finding the driver, etc. with swelling and sunglasses? The clinic says airport transfer is included, but the return flight is still making me anxious. Also, for people who went alone, did you tell many people at home? I don’t want a big discussion with family before I even decide. But also I feel a bit strange hiding it. Maybe I’m overthinking because the deposit deadline is next week and now everything feels too real.
