I understand how you feel. please do take it easy. When born in a country like Nigeria, education is a way out of poverty and in a way a measuring tape among your agemate. however, this new development had ruined your plan and you feel like a failure. it is important to note that you are the only one in control of your feelings. Pls be strong, there could be a silver lining form this. Great men and women had gone through a great disappointment like yours. for example Abraham Lincoln, Steven Steinberg, Albert Einstein. it is not easy to get over the feeling but you have to be strong to be an example to people later on in Future. Also keep a strong faith in God
