A funny feeling, no other description

Tonight, I went in a strange mood. I'm ok now but this by no means thr first time this has happened. It's like something comes over me and I can't put into words, just a funny feeling. Im not sure why, and it just made me feel sad. Like feeling tearful was the only way to express myself because I think sometimes I don't fully understand myself. There was no reason for me to feel sad. Nothing had even happened. I think I get lost in my head too much.

So I went upstairs and changed the bed. My partner knew something was up, and so did I,  but I didn't know what.

I don't know if this is an autistic thing. I'm even doubting that I'm on the spectrum at all and will be paying out a large sum of money for an assessment next month.
