This happened to me but i didn't know jack so i shoved both in my ear! Don't do that! To start of i can see why your frustrated but its only human. Let your ears heal for at bit, i would say sometime near a month, Allow them to relax and use some sea salt soaks, according to heathdawg its 1,4 a teaspoon of sea salt per 8oz. container, if i remember correctly. Soak your ears for 5 to 10 minutes. Now during this process use emu oil, it will help heal your lobes and make them stretchy, preparing them for the next size.
If taken the previous steps, your lobes should be near the ready point to stretch. After all has been said and done take a hot shower, relaxing your ears. Lube up the tapers with emu oil and push them in. Don't sit there fiddle with the tapers and irritate your ear, just simply ease them in. After that let the tapers sit for a day or 2 then once again warm shower lube them up with emu oil and try putting them in. You should be fine and at your next size.
Quick side note, massages with emu oil can help you get rid of scar tissue if you have any. Emu oil can be found almost anywhere including here on BAF!
This is all based of my experiences and things i've learned in the past, if there is anything else i could help you with just let me know.
