mechanical or manufacturing?

It is very hard to decide....when i got 1st choice on Friday, i so happy, never thought i can get 1st choice,mechanical engineering with my CGPA 3.75 only but what i calculate was that i got more then 50% can get 1st choice. But i happy for 1 day only. The next day Saturday evening, i receive a sms from USM that said me getting manufacturing engineering with management instate of my 1st choice. I begin to worry, want to online asap but trap in my grandparents house which have no Internet service and I hope just some technical error. After a while, my friend sms me that he also got a sms from USM that saying getting different offer from the website show in Friday. At that moment, I very worry, getting my 5Th choice make me very down.

When i reach home already at night, i rush switch on my computer, connect to Internet, go pohon@usm.my, log in, saw something i don't really want to see it. I felt very sad at that time. I don't know what to do. Should I reject it to get better offer from upu? Checking many forum, many people same and worst then me, from getting a offer to nothing, from taniah to dukacita. Should I grateful? I got an offer from usm and about 4k people being reject by USM.

Finally i make my final decision, i accept the offer. But 1 of my friend say why you accept it, manufacturing good? From what i see is good but the name a bit i dun like it. I decide to change this course to my favourite course, mechanical engineering.

Getting information how to change course, knowing need write a letter to dean and do it at orientation week. I thought senior will tell us how to change course. I am wrong. I need to take my own initiative to ask senior. Being not dare to ask them, seeing orientation almost over and i already done my preparation. School started already 1 week and i haven't take any action. I start thinking i should change course after 1 semester. but still i afraid changing course so '''mafan' after 1 semester not because usm but are the organizations who help me in financial when i study in university.

PTPTN, if i success change my course, i need stop ptptn loan and repaying back the money only can apply again; kuok foundation, which i need to write a letter of permission to them, they cannot allow me to changing the course; JPA, this scholarship I just apply recently, so i don't know if i change my course what will need to do.

Coming back to Ipoh second time, suddenly my brother ask me, how is your application to change course. I felt very embarrassed because not dare to go ask people about process of changing course. I answer him that i didn't take any action about it then he say why i so chicken one. I also don't know. He say should take some action now or you will never know you get success or not now.

So i decide to ask people in office in my school on Monday. I hope I havn't miss the time of changing course, hope everything run smoothly and i get what i need. I want all the thing done next week. Pleases give me STRENGTH.
