There's no point in consistently worrying about everything. What will happen will happen regardless. So breath, look on the bright side. Have some laughs, fall in love, accept what you can't change, and carry on. To actually live is courageous.
If you find someone who makes you smiles, checks up on you,. wants the best for you, don't let them go. Keep them close and don't take them for granted. People like that are hard to find. LOVE AND FRIENDSHIP.
