Need help with my phone, I am freaking out T-T

[DiamondJ_CS]

I am really sorry if I can't post this here, but please to the mods, this is my last hope.

So I am unable to unlock my Smartphone (Sony Experia E5), because I accidently changed the "screen pattern lock" and I've forgotten it, so I can not unlock my phone anymore

I tried to recover my pictures from my phone by connecting it to my PC with a USB-Cable, but I can't open the files because I need to accept on my phone what to do.

Is there any way I can safely and freely remove the screen lock pattern from my phone OR safely recover my pictures? (If I can recover my pictures, I just reset my phone)

Please help me! I'm so freaking scared and I do not know what my parents will say if they find out my phone is "unusable"

Use google to find the required reset info for your phone … not a game site!

"Use the software repair feature in the Xperia™ Companion application to reset the screen lock on your Xperia™ device."
