Is it normal that when i'm too nervous to go out i wear a disguise?

Whenever my meds aren't doing their thing well enough, and I feel too nervous to go out as myself (acquaintance strangers/colleagues might notice me, so far only one friend has seen through me) , I either dress up as a senior citizen (makeup contours to create the illusion of wrinkles, undereye bags, and a curly silver wig, lipstick, my late nana's clothes, a cane for good measure and thick glasses) , or another girl (either a wavy platinum blonde wig or straight waist length dark brown wig, my hair is medium long and cherry brown, hazel contacts, slight contours to alter face shape, and a fake mole when wearing the dark brown wig. I also stuff my bra). I feel braver when I face the public as a different person, even though this is by no means a small town, just as many men and women feel more confident with makeup.
