So when I was 3, I was diagnosed with autism, but recently I feel like i have Bipolar or both, my father has never been diagnosed with anything but everyone just suspects he has autism ever since i was diagnosed. the reason i'm wondering is because i suffer from a lot of symptoms of bipolar disorder. 

My hobby is i like to write movies, and i've noticed I go through episodes of motivation, confidence and full of ideas and i'll be writing everyday for like a week, then i just stop randomly for months and not write anything even when i really want to, and even when i can't get myself to do any writing i still get ideas but never follow through.

 My sleeping and eating is really bad, i don't sleep until probably 3 at the earliest and 5 at the latest, i'll be doing anything like thinking and just on my laptop.

 my appetite is super weird because i'm neither hungry or nauseas when eating, i just don't feel like eating, i obviously force my self because i have to but never enough because i've lost around 8 pounds recently, then probably later on i'll start weight lifting and gain it back but its hard keep going because i find it difficult to eat that much, it'll be a constant loop. 

I also essentially spend ALL of my money on clothes n stuff like that and never save anything. 

Essentially my mental health sucks at the minute, my weight fluctuates to switching from barely eating to eating a lot and working out, i sleep late and wake up late, i go through stages of creativity and productiveness for like a week then ends with a depressed, sad or dull mood for months and months where i don't go outside or talk to people because of anxiety. i also haven't even had a phone for like 5 months because i feel like i don't need one when i don't speak to people anymore.

Any advice? i want to see if i can i get a diagnoses but it's just difficult getting out right now.
