Answer:
2. No.
Step-by-step explanation:
Absolutely not, think of one time being sad has ever helped you in a situation. The only thing sadness has ever done is make you not want to go anywhere, constantly eat, and stay in your bed.
If you're sad all the time, that could mean depression, and bottling up your depression could eventually lead to some form of hurting yourself, or someone you love, it may even lead to your death.
Whatever's making you sad, you need to address the situation and not bottle it up. Squash it once and for all so you can experience joy again, do not let a situation you're able to control make you want to lose your life.
