Everything's got worse since my diagnosis

I've been recently diagnosed with ASD after troubles with anxiety, depression and concentration.
While the diagnosis has improved the depression, I feel like my anxiety and concentration problems (sensitive to conversations and loud/lots of sounds going on around me) have become worse.

The things that are worse are that I sweat all the time I'm around people and most of the time I have a headache (even when alone), which gets worse when there are conversations happening near me.

I tried telling my parents but they seemed as if they didn't believe me at first, saying that it sounded weird.


Did anyone else have this?
