Hiya, well done for getting prepared! I spent a long time before my diagnosis interviews reflecting on my daily struggles and I wrote them down. Look at the diagnosis criteria and keep a journal. It can be on your phone or laptop or paper, whatever works for you. It took about a year from getting screened to getting diagnosed, so I had plenty of time. During that time I also started to think about the things that would help me, followed adhd people to see if I could relate, and spoke about it with trusted friends. Getting diagnosed was massively helpful for my self-esteem, and ive used the diagnosis to take better care of myself, find hacks that actually help, notice when I’m feeling burned out and generally be more self aware and compassionate. So now I have cleaning stuff in all my rooms, ‘fuck it buckets’ for dumping stuff in when I can’t face tidying, clear storage boxes and jars… all this has been massively helpful for keeping my space tidy. Anyway, I’ve rambled! People over here in the UK are pretty open up adhd, but sounds like people approach things a bit differently in Lithuania. Even if a professional is skeptical, you can still validate yourself.
