In your 20s, you will face some of the hardest tests Allah has written for you, it is important to hold on to your faith in Him through it all. Dont lose belief in yourself either. Not every hardship is meant to break you, some are meant to shape you.
Allah knows your pain, your tears, and your struggles. He sees your efforts. Allah has not left you He is preparing something good for you. Sometimes hardships are a blessing, and sometimes they are a lesson.
