I want to give up

I have literally applied to over 60 jobs at this point within the last 2 months and have done over 15 interviews. It seems like no one wants to hire me. I’ve redone my resume countless times and say everything they want to hear during interviews and I never ever get the news that I’m hired. It’s not even like I don’t contact them after the interview to check on anything, I do and it’s always the same “I’m sorry but we have decided to go through with another candidate.” I’m not even applying to like corporate jobs or anything like that. I’m literally applying for the most basic jobs you can get like cashiering, food service, etc. and none of them want to hire me. I even tell them I’m open to overtime. I have even gone to the second interviews when they ask and they always go “perfect, we’ll call you for when you can start.” And they never ever call back and when I call for an update it’s either the “im sorry we went with someone else” or “sorry forgot to send this to HR, we’ll give you a call.” I truly and honestly want to give up.
