Think i'm autistic but corona virus stopped diagnosis and now i'm really struggling.

I can't say i'm autistic but i'm pretty certain I am. I'm an 18 year old girl and understand that autism for men and woman are very different. I have been diagnosed with ADHD. During this time of life I am finding it insanely hard to keep doing anything. I'm loosing the plot. Over reacting at most things and finding it almost impossible to be interested in anything. My boyfriend doesn't understand and isn't aware how hard i'm actually finding this all. I'm looking for somewhere to relate and somewhere were my thoughts can stop even for a second. Nothing is in place anymore and everything's different.
