How can i not hurt her feelings?

ok, i have an instagram account and i follow one of my friends, whose name is claire. the problem is claire is extremely negative. most of the times, she posts really depressing and scary pictures. she'll have pictures of people cutting or hanging themselves, or she'll have a picture of her with a sad caption that says that she is so ugly (when in reeality she is very beautiful). the thing is this is affecting me to the point where i start thinking like her. she does not contemplate suicide. her only problem is that she want so much attention, and she will stop at nothing to get it. like for example, many of her so called friends ditch her and she'll cry and confide in me all the terrible things that they did to her. and then boom! she's back with them again. this cycle keeps on repeating itself.

so anyways, this is affecting me and my mother wants me to unfollow her. but, knowing claire, i kno tat she will tink that it's the end of the world and hate me forever. so how can i not hurt her feelings and at the same time unfollow her?

p.s. i will still be friends with her, but not to the point where my feelings get involved.
