Most people derive meaning for living from their work and their family (marriage & children). If you don't have those, not even as goals to work towards, no wonder you are suicidal. ("But he who sins against Me wrongs his own soul, all those who hate Me love death" Proverbs 8:36). You may want to reevaluate your beliefs about life. To most, the fulfillment of those goals (based upon their religious faith), more than compensates for the struggles and hardships involved. If you choose to go another way, that's your choice. You are still young enough to change your choice. Why are you complaining about it here?
Here's a clip about an excellent movie I recommend, "It's a Wonderful Life" (1946).
