Many factors can contribute to a missed period. If you have concerns, check with your doctor, but if it's been that long, you're probably ok. Nothing anyone can write here will help you get over your stress so you'll need to talk to your physician. If there is a chapter of "family planning" in your area, you might be able to go there to see about some assistance with this. You need to talk to someone who can help you with this. Find a counselor, minister or someone you can trust who will be understanding. A lot of the recommendations from me or others will be dependant on your age and what would be appropriate advice for you.
