She is affected.
75-76 You glow with bright light in a 30-foot radius for the next minute.
Any creature that ends its turn within 5 feet of you is blinded until
the end of its next turn.
She is a creature within a radius of 5 feet (0 even, she is the point of origin) and she will be blinded. She isn't exempt from effects unless the description states otherwise. If someone casts fireball on themselves, they will be affected. A radius effect always includes the point of origin, unless it is explicitly stated otherwise. The effect would have to establish that you are exempt from the radius of creatures that forms an n-sphere on which you are the point of origin of the diameter.
A radius is a well-established term, and it includes the point of origin and the diameter of the shape. Further, it is well-defined what in that radius is affected: all creatures are affected. You are a creature, and no further text is required that specifies this.
For all purposes, it is phrased like a Sphere (PHB 204):
You select a sphere’s point of origin, and the sphere extends outward
from that point. The sphere’s size is expressed as a radius in feet
that extends from the point. A sphere’s point of origin is included in
the sphere’s area of effect.
A sphere’s point of origin is included in the sphere’s area of effect. This is also true for aura type of effects which have the person as the point of origin, and when you compare it to other rolls on the Wild Magic Surge table (PHB 104):
95-96. You and all creatures within 30 feet of you gain vulnerability
to piercing damage for the next minute.
You will notice that the wording is distinct. It makes this explicit that the 95-96 roll doesn't use a radius and indeed would have to establish that you are included in that effect, and it does exactly that.
The 69-70 roll would not affect her because it doesn't establish that it uses a radius or that you are affected.
69-70 Each creature within 30 feet of you becomes invisible for the
next minute. The invisibility ends on a creature when it attacks or
casts a spell.
Compare moreover how the 89-80 invisibility effect is also distinctively worded that you are affected, not creatures within a radius or creatures within x feet of you:
89-90 You become invisible for the next minute. During that
time, other creatures can’t hear you. The invisibility ends if you
attack or cast a spell.
