Unhappy [Q] Fell on the toilet

So I was stupid enough to put my phone in the back pocket of my jeans, as a result I forgot I had it there and it ended up on the toilet!

When I got it out it kept turning on and off and the touch was still working. I turned it off as soon I could and gratefully it stopped turning on and off!
I've put the phone in rice for about a day and a half (taking SIM card part away), try to turn it on and it shows the lights of the touch buttons and it turns the screen on but it gets stuck in the Nokia logo.
I really don't know what to do now! I've tried several times with charger/off charger/connected to the pc/etc. Eventually I gave up and put it in the rice again.

Should I put it in repair or something or should I just give up? I mean, maybe the cost of repair will be so high that I might just start saving money to buy a new phone....

Please help me if you can!
