I've been following up on your case since and have chosen to be ignorant of it; it's not my business, though. But judging from your story, you really don't have anyone to blame but yourself.
 
Let's assume you generated a wallet using any of the non-custodial wallets out there: electrum, metamask, or any other. And once you generate the address, a private key or phrase is issued out to you with a warning message to store it safely in case you misplace it or by mistake it gets into someone else's custody. That's on you. So if you misplace it, will you go back to the wallet provider and request that they give you back the key? When there was never any agreement that they back up any of that your data?
 
If you lose your private key, you lose your money, and there are no two ways about it, unless there are people who will feel pity for you and help you send a few coins in order for you not to die of a heart attack. If not, just forget about the money; that's a price you have to pay for your carelessness.
