ALL PHONE TECHNICIANS

Hi, I have an IPhone 5s which I reset every now and then if my phone has no space left. I've done it again and I went on it and stuck on Activation lock. I do not know my first account I made, I guessed it and it stated that I can't log on as it is disabled as being secured. I've tried to change the password but I need to log on to the same email to get it changed! Is there any way I can totally wipe my phone including the activation lock so its like a brand new phone where I can create a new icloud account? Is there anything I can do?

No.
That's the basic anti-theft system and it is totally impossible to bypass it.

You can reset your password using a web browser on a computer:

(The phone password would normally be the same as whatever you use in the app store, any time you add a new app…)
