IPhone 4S help, deleted messages?

So I had messages from Friday and it was with the guy I like, saying how he feels about me, and I deleted the messages by accident. (I'm Really mad now)
And when ever I go to search and type up keywords from it, it shows the messages but if I click on it, then it just takes me to my messages, and not that message…
So it's like it's there… But I can't see the full thing.
Please tell me there's a way to get my messages back, please Please help if there's (ps I didn't back it up or anything D: )

I think this may help, humor is the best for healing

It isn't THAT important. At least you know how he feels about you…

Unfortunately, they're deleted. Forever gone. Sorry kiddo.
