Hi @user863778
You mentioned that you “roughly know” which school you should choose, but your mind keeps going back to questioning the decision, especially at night.
It sounds like the decision itself may not be the only difficult part here. The uncertainty after making a major choice seems to be affecting you quite strongly as well.
The part about seeing your friends choose the other school also seems important. Sometimes even when we already have our own preference, seeing people around us make a different choice can trigger self-doubt very quickly. The thoughts can become:
“What if they made the better choice?”
“What if I regret this later?”
“What if I cannot cope?”
You also mentioned worrying about coping even before school has started. When anxiety builds up, the mind tends to focus more on possible negatives and future problems. It may feel like repeatedly thinking through every scenario will help you feel more certain, but after some time it usually increases stress instead of helping clarity.
One thing that stands out is that you already said you “roughly know” which school you want. That usually means a part of you has already considered your own needs, preferences, and priorities. The difficulty now may be trusting your decision while accepting that no choice comes with complete certainty.
In Singapore’s context, university decisions can feel very high stakes. There is often pressure to choose the “correct” path because it feels connected to future success, opportunities, and even identity. Because of that, it makes sense that this decision feels heavy.
At the same time, coping in university is not determined only by the school itself. A lot of adjustment happens gradually after entering the environment, through routines, support systems, friendships, and learning how to manage challenges over time.
I also want to point out the sleep issue because once anxiety starts affecting sleep, worries often feel more intense and harder to manage. It may help to notice when thinking about the decision has shifted from useful reflection into repeated overthinking.
You do not need to eliminate all doubt before making a decision. Most people still have some uncertainty even after choosing. Perhaps a gentler question to ask yourself is:
“Which option fits me better based on what I know about myself now?”
That may be more helpful than trying to find the one choice that guarantees no regret later on.
