The popular reaction to an idea has no bearing on its truth or otherwise. Just because people ridicule you because of your faith does not mean that it is untrue. Actually often those who ridicule Christianity have little to no understanding of what Christians believe. It isn't as though people have often tried Christianity and found it was no good; often they have not really given it much thought.
Secondly you are not unique if you are ridiculed for having faith. If one was to project themselves into the first century and live amongst the early church they would be projecting themselves into a time and place when hostility to faith in Christ came from every side. The Roman authority and the Jewish authority were deeply hostile to Christianity and yet even then because of the resurrection the church thrived and grew.
Thirdly attend to your support structure. Doubt can lead people to isolating themselves from their support network but when faith is under fire by the ravages of doubts, it is the best time to engage closely with people who have a strong faith and seek their support and help. Get involved, get connected, don't go it alone.
Doubt is like spoiled child, the more you tend to it, the more attention it demands. When doubt comes into the picture don't get passive, get active. See it as a health warning and seek renewal and revival in your spirit. Don't let doubt dim the fire of faith.
