Not Receiving an Email to Change my Forgotten Password

Hi there, my original account is the one with username hashimtmahmood About a week ago I tried to change my password to something stronger, but the feature wasn't working on my account whilst logged in, so I opted to click 'forgotten password' and set up a new one that way. I deleted my old one from my password manager and awaited an email allowing me to enter my new one, but I haven't received one. As I deleted the original password in the hopes of receiving the email to enter my new one, I can't regain access to my original account. Would it be possible to send a forgotten password link to my primary account (for privacy purposes I won't enter my email into this post, but its associated with my username: hashimtmahmood) This second account that I'm using is only temporary, so after I have this resolved I will delete this account (hashimtmahmood1) Thank you!
