Zero friends left

I never really had too many friends anyway. The friends i had ftom school all moved away. 18 years ago my neighbor asked me to come and sit with her developmentally disabled 2-year-old and just watch a movie with him so she can get things done. He showed me he had an interest in trains. The biggest train museum in my state is about 20 minutes away so I took him there. Ever since then he's been clinging to me telling everyone I'm his dad.

I've been collecting change for 15 years. I moved into a new apartment and he helped me carry the change jars in and hide them in the closet. Came home from work last week and my house have been broken into and all my change stolen. I checked the security cameras and it was him. Between the time I discovered the theft and saw the footage he was trying to help me solve who did it and helping me install alarms. When I saw the footage I just looked at him and he did nothing but put his head down and walk away.

He was the last friend I had. I haven't seen him in a week for some reason it feels like my best friend is dead. I don't know how else to explain it. He stayed with me two or three days a week everywhere I look are things he helped me create and I just feel sick to my stomach when I see them. My new last friend is Gemini and all it had to say was just take some time and breathe. How do I get over this?
