Please help with my OSAP loan!

I am in a very difficult situation and I'm wondering if anyone can help me out with this.

Due to circumstances I had gone to bankruptcy in 2009 January. I have just been discharged this year May. I'm trying to rebuilt my credit and not make the same mistakes I have made in the past. My OSAP loan was not included because it was not in the 7 year point at that time (now it is). At the time I was filing for bankruptcy, I did not know how to deal with my OSAP loan. I completed my studies in 2005 and was sending in the repayment assistance forms each year. After I had filed for bankruptcy, In 2009, I had called into national student loan office and asked what to do with my loan and payments. They had told me since I went to bankruptcy, my account was frozen and they cannot tell me what to do or accept any payments. However, I wasnt going to make any payments, I had simply called to inquire about what to do next with osap. They did not inform me I can keep sending repayment assistance forms and nor that the government would pay for my interests. They simply told me they can't accept payments or anything and I would have to deal with my trustee. Nothing about the repayment assistance options were discussed with me, or else it's not a big deal for me to send those forms each year, which I was doing before. So, I had stopped sending in the repayment assistance forms after that. I contacted them again in 2010, and I was pretty much told the same thing, nothing about me to keep sending in the forms. After I was discharged this year 2014 in May, they sent me a letter saying I had to pay close to $7000 in accumulated interest immediately for them to update my account. They had also told me that if I had sent in the repayment assistance form each year, then I wouldn't have had to pay this much in interest and that the government would have paid for it, which does not make sense because I was not informed of this before. They are saying, I was sending it before why didn't I just continue. However, I did not know I could continue sending in the assistance forms, especially after I was told my account is frozen until I come off bankruptcy. So now, I'm left to pay immediately the interest or else it would keep building up and then it would be sent to CRA for collection. I am unable to pay the $7000 immediately. I was just discharged, my credit is not even built for me to apply for any loan. I cannot borrow that amount from anyone. I am a single mother with a baby. As much as I don't want to be, I am on social assistance temporarily. I was just diagnosed with a chronic illness of rheumatoid arthritis which prevents me from working for now. So basically I am in a very bad situation. I am in no way to come up with $7000 or I don't even know how I will be able to make payment arrangements. I don't think my medical condition will be considered for disability forgiveness as they told me for that I would have To be severely disabled. I don't know if my condition will get worse, maybe it could maybe it might get better with medication. I had explained all this to the national student loan service, however, they said they can't do anything about it. I had asked them, how will I pay for all this in my current situation? They i just have to come up with the $7000 interest or it's going to CRA and more interest will be built up. I feel it's not fair because I wasnt properly informed and considering my situation now, I'm still being forced to pay. If I was told to keep sending in my forms, all this interest wouldn't have been built up. I spoke to a manager as well, and he also said I should have known and since I contacted them few times, I was aware of it? It seriously does not make sense to me, and I do not know what to do or who to contact for help. My total osap amount is $32000 and the interest which accumulated is $7000 and $400 will continue to accumulate each month. A representative had also suggested for osap forgiveness because of my disability, but she also had stated my disability had to be severe whereas I cannot function at all on a daily basis. I had even asked to add the $7000 to my principal and if I could apply for interest repayment again. They said no. I asked if I could make small payments towards my loan in whole, they said no. Basically they gave me no options. What can I do about this? I don't know who to ask for assistance on this. I feel my situation is not being considered fairly. Please if anyone can assist me with this, I would very much appreciate it. Thank you for your time.

My lawyer said at the time of bankruptcy it should have been 5 years, not from now. However, can we even go back and include it in an already discharged bankruptcy? Would speaking directly to HRSDC instead of national loan centre be any helpful? I feel so helpless.
