What Should I do after MBA and before joining Date. Still have 50 Days at home

I have completed my MBA and also got placed. but joining date is too late. and staying at home with parents but without any purpose was kind of manageable. But lately i have nothing to do. My mental health is deteriorating, and I get irritated from everyone in a second and don't really wish to do anything it's literally very depressing and scary to undergo a transition from this zone to a sales job.
Will appreciate some genuine advice!
