7 month old sleep issues

My LO will be 7 months on Wednesday 
 I have never co slept with her EVER!!.. till last week 
She won't sleep anywhere but next to me in bed. Seriously I don't know what happened. She used to get sleepy I'd put her in her cradle and out she'd go..no issues 
now it's crying like crazy till I pick her up. I try 20 more times throughout the night and nothing, till she gets in bed with me. She's been super fussy, clingy, like I can't even put her down walk out of the room sometimes without her panicking 
 She went to sleep and an hour later screamed for over an hour. Husband had to go out and get some gas medicine (mylicon) since Little Remedies is all I had and doesn't work, as she past some gas before hand and curling her legs up everytime I touched her belly she'd scream. I've been dealing with gas problems since she was 2 weeks old but last two weeks have been hell with sleeping Idk if most is gas, lonely in her own crib (own room) or her cradle, growth spurt, or teething  but I'm ready to ship myself to Australia, take a box of benedryl and sleep for a week straight 
What went wrong 😴😩😭
