50 pounds in 5 months??? PLEASE HELP

Can someone PLEASE tell me how i can lose 50 pounds in 5 months or even 6? I just need to lose weight before summer and get my summer bod going. I have recently gained so much weight at one time & it’s really taking a toll on my body. I’ve NEVER been one to struggle with weight because i’ve been skinny my whole life. I just really need some help because since I haven’t had to try to keep fat off, i don’t know how to get it off because i’ve never went through this. If anyone has ANY tips, workouts, literally anything that can help me, please comment. I am IN SERIOUS NEED of help.
