@AMe, your friend is under a lot of stress at the moment and this is quite understandable.In terms of waiting on CBT, if your friend has been in pain for a couple months, why wait?
Although you have mentioned your friend has been suffering with hyperacusis for a couple of months, I will also assume this person is experiencing tinnitus. Both these conditions can make a person feel they are riding an emotional roller coaster. What usually happens for a lot of people in the early stages of hyperacusis and tinnitus, is that their emotions will settle down with time. Many people naturally habituate within the first 6 months to one year without any treatment at all for noise-induced tinnitus.
I advise your friend to talk to with his/her family doctor who is likely to recommend medication to help with lowering the stress so it becomes more manageable, this will also have a beneficial effect on the hyperacusis. As already mentioned, hyperacusis often improves with time but one can also use low-level sound enrichment to treat it as explained in my post: Hyperacusis, As I See It.
One of the worst things for your friend to do in these early stages of tinnitus and hyperacusis and in a heightened state of stress, is go online looking for CBT counselling as it's unlikely to yield any positive results. The person they will be dealing with does not have a full background of their medical history. Treating hyperacusis and tinnitus is not a quick fix. It is patience that is required; not haste. This is the reason most ENT doctors advise tinnitus and hyperacusis patients in the early stages to wait and allow things to settle down by themselves before medical intervention, as long as the person isn't experiencing dizziness, deafness, balance problems or anything else untoward within the auditory system that is causing the tinnitus and hyperacusis.
If the tinnitus is noise-induced, which is often the case, leaving things alone for a while is the best treatment as explained in my post: New to Tinnitus, What to Do? It is often recommend a period of four, preferably six months should elapse before starting long-term treatments such as CBT or TRT.
Please advise your friend to talk to their GP (family doctor) who will probably advise a referral to ENT. This is the right and proper thing to do in the early stages. Seek medical treatment in-house before going online and consulting with people that do not have full knowledge of your medical history.
Please print the articles that I have recommended in my previous posts and the two I am going to mention below and give to your friend to read. They are a form of counselling and will help alleviate some of the stress they are going through, by understanding tinnitus and hyperacusis better and the way they can affect a person's mental and emotional well-being. This coupled with medication (if required) by their doctor is all that is needed at this time.

All the best and take care,
