Usually the longer you have had an uncorrected hearing loss the more challenging you will find it to get used to your hearing aids. That said, you have 2 of the most important ingredients there: Determination to make a good job of it and an audiologist who is working up your prescription gradually. Part of the difficulty can be that for all sorts of reasons we want to rush into wearing the aids full time everywhere, whether you want to get the most out of a short trial period, your relatives are so pleased you have finally done something they now expect you to wear the aids all the time, employers likewise.
Most adjustment schemes recommend you start by sitting quietly around the house with your hearing aids for a few hours. For the first little while most fitters recommend you take them off to go outside in a busy street. Work your way up to the more challenging environments, don’t expect to be able to tolerate your new hearing walking along the side of the street or in a busy restaurant in the first week or so.
You might also benefit from doing some work that actively focusses on hearing and listening. Put things on the computer and TV to challenge yourself to listen to the content as best you can. I have used a few cochlear implant rehabilitation programs on the computer, as their progressive nature with ability to give you a score afterwards shows you how you are doing.

When you have relied on other clues for a long time you forget the skills of hearing and listening, you need some time to get these back, so be mindful of your expectations and those of others, who may wonder why you can’t just strap on a couple of hearing aids and immediately not be HOH any more.
Keep a note of what you struggle with, it will really help the audi in future adjustments if you can be quite clear about what you found difficult. You get there on the day and find you can’t remember or explain it properly! It may be that the first hearing aid you try just isn’t the right one for you, so assuming you are still in a trial period be open to the idea of swapping to a different one. They may be the same “on paper” specification, but just as some people like one entertainment system better than the next one the same with hearing aids, what I can’t stand you might like. Only you have your hearing, you are the one to say.
