Sorry to tell you, but most miners are just in it for the profit. Even if you ask them nicely, they won't include any less profitable transaction in their blocks for free.
The couple of miners that do accept some less profitable transactions for free won't be browsing bitcointalk just to find people they could potentially help.

At this moment, i'm afraid i don't know any free transaction acceleration services that still work... So you're left with either waiting it out, or fixing your own problem by either bumping the fee (if you opted in RBF), double spending the inputs of the unconfirmed transaction, or by generating a RBF.

It's up to you, but if you don't take action, chances of your transactions confirming are slim to none... The recommanded fee at this time is 390 sat/byte for a 95% chance of getting in the next 3 blocks... So 25 sat/byte doesn't have a very good chance of getting in...
