I wonder to be ANGRY or SAD

I am very busy in my work now. Especially doing sumthing when you are not at all familiar. Now is 8.01pm and I am still in office trying to figure out some figures for my budgeting. Although I done it once last year but its with the help of a Finance personnel whom had currently transferred to another department. A director was assigned to 'partner' with me on this was away for business trip and last year he was away on reservist so both years I am left alone. Being very new to finance industry and very ignorant about the terms used, I had to struggle my way out. Now I felt that I am really not cut out to do finance-related jobs? :( Very sad and down now.
My boss is a very nice boss. Despite the fact that I answered some of his questions wrongly, he didnt scold me or reprimand me. I just felt ashame of myself for making such mistakes. Am I really so useless? :'( I told myself not to be lazy already. I told myself I had to work hard in order to see the fruit of my labour...but...I really feel so useless.
My brother and wife signed up for SCV box with my mum's NRIC without her acknowledge. The debt collecting company called my mum and even sent letter to ask for payment. My mum is not really tat educated to handle this stuff and so I took over. 2 months ago, spoken to them to ask them pay back through installment and asked them to liase with the debt collecting company but eventually till now the amount is still there INTACT! FCUK! Wat the FCUK is those FCUKERS trying to do? I got upset and I tell myself I am not going to deal any cases for them. For them, I even resort to borrow money from friend to pay their first installment of Citibank which if not they will be sued too. Stupidly I did it. And I guess I had enuff of their rubbish. So wat if she cries on the phone, So wat if they are in huge debts? I am also in debts since I got married and I had been carrying the debts bloody hell ALONE...for a long period...until I almost wanted to jump down from my 11th storey flat but I had my parents whom I need to take care of. :'( Now, my ex-hubby dun reply or did not receive my sms of asking when will he be assisting me in paying back...and my bro still gif me this shit to handle! My studies also not managing very well cos of my bloody laziness! So..WHAT THE HELL SHOULD I DO NOW?
I was struggling in work to get my budget done, the debt collecting company called again. He tell me all the numbers given (except for mine) are out of service. And my bro and the bloody wife changes number every 3 months dunoe to hide from wat? I know I am in debt, but I tink of ways to resolve them but those bloody jokers choose to HIDE! I wanted to go their flat and tear down their flat already. Now I cant get anyone there.
I called Starhub, I decided to request for a hardcopy of the form signed. I will give them another chance and by tonite if i dun hear anything from them, I am going to make a police report and sued them for forgery and get them both in jailed! I had enuff. If by helping them dun make them realise the seriousness of the situation, I guess they had to spend some times in jail in order to wake up. I know this is bad...but how can I make them wake up??

*prayers*
Dear God,
I know I am doing sinful things again but who can help me resolve this problems? They choose to hide away from problems and leave everything to me! I cant take this stress anymore. I cant work properly with this stress. I cant study properly with this stress. I wonder what have I done to deserve all these? :(
If I cant solve this issue, please let me die and release my stress.

*A-men*
