Can I ask what was your degree? I just wonder if it is a highly portable type of degree?
Hmmm, have you tried to negotiate a 'trial period' with potential employers, where you offer to prove that you are a fit, it's up to you to negotiate the terms of a 'trial period'...
by such a proposal you are signaling/messaging the potential employer...
"hey, I'm hard working, I am confident, and I'm prepared to take a risk to show you (my future employer) that I'm what you need"...sorry if that sounds too corny.
Else, depending on your degree are you prepared to look outside of Nigeria for work opportunities?
Yes, I do realise this poses a serious amount of challenges and hurdles ...am just posing questions.
While I am sure you will continue thinking laterally, you also need to keep bouncing ideas...like you are doing by this post

...and yeah don't worry about the ladies, they will find you...all in good time.
