Yours is a Good Question... and most people have probably asked it at one or more points in their lives. It's been asked here *lots* of times.
Has he stopped bad things from happening to anyone *else* upon this world? Did he stop Jesus from being crucified? Why would you expect him to make a single special exception of *you* compared to every *other* human across all of human history?!
Your basic quesion is: Why do bad things happen to good people? This is a question humans have been asking for as long as humans have lived and have thought about these matters.
Biblically, the book of Job addresses that question. i don't think it comes-thru with any *real* answers (at least of a satisfactory nature, to *my* view).
i don't think a satisfactory answer exists in the Bible *or* in the Qu'ran -- and i seriously doubt you'll get an *accurately* satisfactory answer from any of the Christians, because they've got a false theology, rooted in their concepts of "God" based upon the Old Testament God -- who never *has* been the *real* God.
My answer (written about 17 years ago) is here:

i get *tired* of doing repeats...
If you really want to know what my answer is (it's unlikely that anyone else here has provided that kind of answer) then check it out!
Personally i'm getting *weary* (again) of the repetitiousness in the Religion & Spirituality section of *Yahoo Answers* and feel like it's time for me (if i am *wise*) to leave here for at least a month... better a year... perhaps best, *never* return, because i think, overall, i'm really *wasting* my time here... but, recurrently, i get the urge, again, to *try* to be a bit helpful relative to *serious* questions being asked from genuine Seekers of the Truth.
It can be a *rough* life on this world. Circumstances here are often *cruel*.
Jesus once told me, "When you die, you have a *choice*." Unfortunately i didn't hear what the choices *were*! (If i were actually a "liar" like a number of atheists accuse me here, i'd make some up, rather than admitting what i *don't* know!)
i *believe* one of those choices is that you can *reincarnate* here -- but you don't *have* to. You have to *choose* to. (If you don't, that's fine! There are all manner of animal souls who *want* to come back as a human. i could *clearly* see that our late dog, Ebony, definitely wanted to be *human*!)
So i *believe* that *you* chose this incarnation that you're dealing with... thus finally it's for *you* to determine *why* you did so. Really no one else can *define* that for you. Part of your reason for *being* here is to define it for *yourself* -- and then *fulfill* it!
All i can assure you of is that all the awful things that have happened to you are going to *help* you define that reason... and enable you to *better* set about fulfilling your life's *purpose* for being here.
The dreadful experiences you have *had* will enable you to deeply, *compassionately* understand all others who have had similar experiences, which, of course, will *qualify* you to insightfully *help* them, once you define the answers for *yourself*. Most likely that's why you have had those experiences.
From my own personal experience i was asking the Biblical God for Answers for about 35 *years* and he never spoke a word to me! But as soon as i started asking *Goddess* for the Answers, *She* communicated to me (telepathically). After that Jesus started communicating with me, Mary Magdalene did likewise, and Goddess "connected me up" with the *real* Heavenly Father (*not* the Biblical "God") and *He* explained a few things to me. After all of *that* the Biblical "God" started trying to deceive me! -- and threatened the lives of my children.
My life has been an *interesting* "Spiritual Odyssey" -- at least to me! -- as i look back over the past 75 years.
To anyone and everyone i say: *Don't* seek the answers from the Biblical God or *his* book. He gives too many false answers. Don't seek them in the Qu'ran. Go to *Sophia*, Goddess Herself, Jesus's Divine *Mother*, the real Holy Spirit; for *She* truly loves you; She'll teach you everything you *need* to learn, once you establish genuine *communion* with Her. You won't need *any* answers from Yahoo Answers after *that* relationship is established.
My website -- Cosmic Mother, Wisdom's Lovers -- is in *service* to Her -- as are 2 of my Facebook pages (the other two being in service to Mary Magdalene, Jesus's *wife* -- of whom Jesus once told me, "We're *married*. It's *not* going away.")
