Hi @drhira ! This is absolutely right, that happiness and sorrow are a part of life, and we shouldn't let sorrows overwhelm us. I feel great knowing that you're trying to ignore your worries and stay happy.
You're a very hardworking person, and I hope you'll soon get the reward for your efforts. Your concern for your brother and sister's future is a sign of your love for them.

Good things happen to those who think well of others. My good wishes are with you.

stay blessed.
