Hello, I was diagnosed when I was 12 but I'm 20 now. I gave up for a while and joined this forum after starting to see doctors again. I gotta be honest, the whole process can be kind of infuriating sometimes. Some doctors straight up don't believe in fibro, other just throw meds at the wall(e.g. your brain) to see what sticks, others will just completely dismiss your symptoms or tell you you're faking.
I gotta be honest, I think I have hypersensitivity to side effects of drugs, but in 8 years I have not found a drug that's worked for me. I'm not trying to be discouraging; I'm trying to make the point that what has been most helpful has been seeking support(I'm seeing a psychiatrist now) and keeping a good mindset, and trying to apply yourself regardless of how you feel. Just getting out of your house and walking around can help at least your mood a lot.
Don't be discouraged though, the meds available seem to help a lot of people, they can just be hit or miss. Good luck in getting help, I know the kinds of dark places it can put you but just keep pushing trust me it's worth it to just know you can get past it!
