schizotypal or autism or cyclothymia ?

hello i’m sorry this is going to be long. so as a preface i’m diagnosed with major depression, general anxiety and social anxiety. but i think i could be misdiagnosed or have something else.

i think i might have cyclothymia and i’m currently discussing a diagnosis with my therapist. i have intense mood swings; periods of strong sadness where i just can’t get myself to do anything and periods where i’m super energetic, talkative, and productive (but not mania).

but it doesn’t explain everything i experience? my whole life i’ve felt so different from everyone, like everyone else knew how to interact with people and i didn’t. i observed other people to learn how to be normal and i’m always acutely aware of doing anything “weird.” i know i’m not human, i mean i know i biologically am one, but i feel like an alien that’s been put into a human body.

i see patterns everywhere that have special significance for me, and i only i can understand them. i see signs and omens that the universe shows me. reading about ideas of reference for the first time made a lot make sense. i always see people make eye contact or little gestures and i think they’re criticizing or making fun of me. it makes it hard to be around people since there’s these little signs and hints they hate me.

also, a couple years ago i had a depressive episode and this became so much worse. i thought my life was a social experiment, everyone was in on it and watching me and studying me. i worried my family was replaced by doppelgängers, everytime i was in public i felt watched. this gradually went away despite not receiving treatment for psychosis, and only being given antidepressants. though i had the magical thinking before and after this.

i relate to schizotypal traits and autistic traits, but i’m not confident i even have either. but you can’t be diagnosed with both right? and if i had cyclothymia i couldn’t also have StPD? i’m not asking for a diagnosis, just wanted to hear others’ thoughts on what’s wrong with me i feel so lost.
