It is too bad you quit the course. There are a lot of ways to work around your hearing loss. You may want to check out www.beyondhearingaids.com they have a wide range of FM systems and other products that you may find helpful. Remember too, you have a right to request accommodations. If your class was at a school,hospital, or business, they have an obligation to provide you with accommodations such as captioning, sign language interpreters, FM systems, etc.
Many people who experience hearing loss as adults go through a period of denial, and then adjustment. You may also want to check out www.alda.org The Association of Late Deafened Adults is made up of people who you may find have had or are having experiences very similar to yours, and it may be encouraging to research some of the information and resources available through this site.
I do disability consulting for a living, so if you want any additional support, PM and I would be happy to discuss this further.
