Just been diagnosed at 24, HELP !!

Hi

I am a 24 year old girl and I was diagnosed with autism about 3 weeks ago after being misdiagnosed with anxiety and depression my entire life. I am very happy and relieved with my diagnosis but feel completely lost and have no idea what to do next. I have recently heard of PIP and have considered applying, other than that I have no idea what kind of support or help I can receive. I work full time and live with my boyfriend, my parents aren’t very supportive as they just feel “guilty” they didn’t notice sooner. If anyone has any advice on what to do next I’d be extremely appreciative, thank you so much.
