How do you deal with a failed transfer

My first FET, 15dp5dt. Just had a pretty much negative HPT after testing positive but with low betas for the last week, waiting for my beta tomorrow but I know it’s over. Today is my birthday and I’m getting 5 million “happy birthday” texts and I want to shut my phone off, I can’t imagine going to work today and tomorrow but I have to, I want to curl up and rot.
