Hello
@namers, since I see that you are a new member here,
WELCOME TO CF
As for your fear of what "
terrible end" God may have in store for you, what could that possibly be

After all, as a believer, your "end" can hardly be described as "terrible", yes?
(seeing that it involves living out eternity in never-ending joy, bliss and happiness in the presence of our Abba / loving Heavenly Father
).
As far as suffering/persecution goes in this life, remember that the very same One who chose to come here and die that horrible death on the Cross for you
(to save you so that you wouldn't have to live w/o Him, nor He w/o you, in the eternity to come), continues to love you and to want the very best for you
(BTW, the Bible tells us that we are loved by Him with an "everlasting love", which means that there was never a time in eternity past when He did not love you, nor will there ever be such a time, now or forevermore
). So what better situation could you possibly choose to place yourself
(your life) in than in His precious hands, yes

Of course, no one likes the suffering and persecution that they are (or that they may be) facing, but as difficult as it sometimes is, suffering in this life has MANY benefits/blessings .. e.g.
Hebrews 12:7-11. God knows, for instance, how brutish the love that we have for this world really is, so He uses the fittest means possible to draw us back (which oft times involves suffering), to turn our focus away from this world and its lusts and back onto Him where it needs to be (and back onto our future life with Him, as well).
Have you talked to God about this? If not, you should do so .. e.g.
Philippians 4:6-7 (and your pastor as well).
It is, perhaps, interesting to note that the Apostles felt it a great honor from God to be
counted worthy to
suffer shame for His Name .. e.g.
Acts 17:27-42 (see v41 in particular), but such an understanding comes along with a greater maturity in the Christian faith. As Pastor Charles Spurgeon once said (in echo, I believe, of his understanding and life experience concerning
Romans 8:28),
"I've learned to kiss the waves that throw me up against the Rock of Ages" 
God isn't going to give you anything to do that He knows you can't handle. Remember too that you are not at the spiritual level, living at the time, or in a position in the visible church that the men that you mentioned in your OP were (Peter/Paul/the Apostles), so you can be pretty confident that what they experienced was FAR more difficult than anything that God will ever ask you to face.
Finally, all of us want to grow in our trust/faith in God, and this "fear" that you feel right now may be a very good thing, as it may be the way that God has planned for you to to take baby steps (if you will) to accomplish that, to begin to move in the direction of trusting Him with your entire life, like you have never been able to do before.
God bless you!
--David
Proverbs 3
5 Trust in the LORD with all your heart
And do not lean on your own understanding.
6 In all your ways acknowledge Him,
And He will make your paths straight.
