Default [Q] Partitioned xperia m internal SDcard

First off let me apologize if my thread is in the wrong place (i'm new) anyway i have an xperia m (c1905) i bought an external sdcard to install apps on and what not but then i hit the 'you cant do that now' wall i i rooted my phone and installed Aparted and the like, i went through the process of setting a partition on the sdcard and found it didn't work so i gave it another go and again it didn't work so on the third try i made a huge mistake, i stupidly partitioned my internal memory and didn't realise until i had shut my phone down to then turn it on and see if it had worked this time, now of course my phone is as dead as a doornail, no flashmode no fastboot mode no charge no computer connection.... so my question is... is there any possible chance it could be related to something else and possibly fixable?
High hopes i know but i would like to at least try and bring it back to life
