1 year old help!

I have two girls one 3 one 1, my 1 year old constantly crys. She doesnt like to be left for two seconds. She wants picked up 24/7, she wont play alone and now wont stay in her crib all night. 😩 I cant get anything done, no sleep and not a minute to myself. Its wearing me thin. I have tried everything idk what else to do. I cant even get ready in the morning. Im starting to lose my mind. She has to be on top of me anytime were in the same room lol. Please help me no rude comments. She wasn’t always like this it started about 11 months. TIA!!
