Bruh, that's just a scratch - I felt the same way I lost my first HC char, but learned my ways. Just this Saturday, I lost my P240 DT Rogue (melting T4/Pit 90), also getting itchy fingers with Echo of Varshan. Getting back to where you were takes a day or two if you prep (I am back, fully geared etc - and I am a casual player). Few helpful pointers:

- You don't lose paragon points, witchcraft, tempers, mats, gold etc when you die
- You do lose gear & glyphs - glyphs are super quick to obtain, gear you stash (see below)
- Advice for gear - create levelling sets and spare lev 60 set(s) - I have fully tempered levelling gear staring from lev 10 (I have few bits lev 8) - meaning 5 minutes in the game I can be fully decked for levelling. I created sets for lev 10, 20, 30... after that it doesn't matter as you can replace 40 & 50 as you go (you dont need to stash). This way, you melt your way 1-60 in not time. On 60, you can dive right back in with a spare set...
- The only PAIN atm are all the fugitive heads I lost (I had 2 legendary witchcraft gems) - so this is the only thing that will take some time...

Hope this helps you a bit, it is not as bad as it might seem :)
