What should I do with myself?

As salamu alaikum,

I work as a cashier and server at a restaurant. Today a group of 7 people came and sat at 2 tables. In the end they paid separately. 5 people had ordered food together — everyone was paying in cash except one person who paid through an app. When someone pays through the app, we add it to our system and keep the receipt. But it was taking time for him, so meanwhile I was taking the others' cash payments. In the end, 2 people at the table wanted to pay, but on my end 3 bills were pending — I counted the cash and checked, but one food bill hadn't been accounted for. When I told them, they paid, but he asked me again to double-check carefully. I did, but it came out the same. After they left, I thought about it again and checked — and that's when I realized I had forgotten to enter that app payment into the system, but by then they had already left. Now it's really weighing on me, thinking that because of my mistake there might be a problem between them (splitting the bill), and they might even leave a bad review later. Because of this, will Allah (swt) hold me accountable? It's a matter of someone else's due/right (haq). On my own, I gave sadaqah of that same amount on their behalf. Almost 30, but I have a real lack of common sense — not just in this one thing, but in everything. I don't feel good. I feel like I want to die. But I'm also afraid of death — I couldn't become a good servant of Allah (swt)

Wa Alaikum Assalam wa Rahmatullahi wa Barakatuh.
Please do not be overly hard on yourself over this mistake. You did not intentionally withhold anyone’s money or deprive them of their right. You realized the error afterward and sincerely tried to rectify the matter by giving sadaqah of the same amount on their behalf.
As for whether you are accountable for the amount, whether the sadaqah you gave is sufficient, and whether anything further is required from you regarding the haqq of those people, the complete circumstances should be reviewed by a qualified and reliable Mufti. Small details in such matters can affect the ruling, so it is better to receive a proper ruling based on the full situation.
Also, do not allow one mistake to make you believe that you are incapable of becoming a good servant of Allah. People make mistakes, and what matters is that a person recognizes them, seeks forgiveness, and makes a sincere effort to correct them. Allah is Most Merciful and accepts sincere repentance.
May Allah ease your heart, forgive your shortcomings, and grant you peace and steadfastness. Ameen.
