Emotional Support 😭

So, I got into lums like in first list.Applied for financial aid but didn't get any.We fall in upper middle class so it was quite expected.My fees is getting paid but I fell like do I really even deserve it? They told me that if I really want to return the favor I should have a decent gpa and if I can I should also come in dean's list(they don't pressurize me at all). It make me feel like burden like they are doing a lot for me.I got into SDSB. Having FSc background ( pre engineering) not knowing much about business , don't even know how to use excel,Canva,word or even power point.Now, I am very depressed that is Lums really going to be worth it as many people say that lums is not like what it used to be and how can I get a really good gpa? And from where should I learn excel , word ,etc.Also, I have anxiety issue and my voice starts trembling while giving presentations.Also, I know that in Lums you have to be confident enough to sit with opposite gender but I am not even good at it.And even talking to opposite gender make me shiver(typical enough, I know. But I haven't grown in such environment and have no confidence).My siblings are studying from top tier universities as well. They are quite confident and good at present, have a really nice gpa but I am not like them so I am kind of worried will I really be able to survive.I cannot even sleep at night because of this stuff please guide🙏🙏
