TW: mention of psychosis

Almost two years ago, someone I was close friends with when I was a teenager posted a gofundme for himself &amp; mentioned that he was diagnosed with schizophrenia. He is a few years older than me (&amp; I am a woman who never really had male friends) &amp; when he graduated high school we lost touch. I haven't talked to him in about 5 years, but he was the type of person that was so outgoing that if he saw me on the street he would totally say hi &amp; want to catch up. When I saw his gofundme, I donated &amp; assumed he was going to be okay. 

I don't live in my hometown anymore, but I am back for a week visiting my parents &amp; while at dinner I saw him at the beach &amp; he seemed to be homeless &amp; having an episode of psychosis. My knee-jerk reaction was that I didn't want him to recognize me &amp; get embarrassed. I have had episodes of psychosis &amp; embarrassment was the last thing on my mind during those times, but the idea of him thinking someone who once knew him was gawking at him was really upsetting to me.

I was thinking of riding my bike to the beach tomorrow &amp; giving him some food or money or something but that feels stupid. I saw him at the beach today, but I don't know if he will be there tomorrow &amp; if I do find him, will my presence cause stress? My fear is that I will cause him more harm good because I want to feel "better" about his situation, but it's not about me. I don't know everything I think of feels stupid, but I just want to be kind to him. He was always so kind to me. 

I know everyone is different, but let me know if you have any advice. thanks
