It can be very tempting to put on a smile and a happy face, even if you don't feel like smiling, when around friends and family. You mentioned that you may have trouble expressing yourself. Perhaps what you mean is that you are a little uncomfortable showing your emotions, or sharing your feelings with others. Some people are quite simply more quiet and reserved than others. Nevertheless, if you feel depressed, or melancholy on a regular basis, you really do need to try to share your feelings with someone who will lend an ear and you may find that simply telling someone else of your worries, or problems, will help lift your spirits. The danger for some people who choose to keep all this to themselves is that their daily activities, their work and relationships are all affected by this depression and some try to solve these problems by taking medications.
Don't forget that your family and friends do not always expect you to be perfectly chipper. Everyone has problems now and again and the best solution is to confide in someone you trust. If you have a best friend, try to open up with him/her and discuss some of your concerns. A true friend is there to listen and offer encouragement, so try not to be too self-conscious and don't worry that you are putting a burden on someone else. If you do not feel comfortable talking to a friend, visit your school's counsellor if you are a student, talk to your teacher, or a professor, or if you belong to a local church (and even if you do not) contact the pastor and just ask him or her to sit down with you. All of these people should be willing to listen, and none of them will charge a fee.
