why don't my friends I knew yrs ago have an interest in seeing me?

I moved from where I used to live a month ago. I spent a lot of money on movers and the train to get here. I lived here yrs ago and had a lot of friends here. I had filled out something with housing and I couldn't stay where I was cause I couldn't sleep nights cause of trains and loud music from neighbors. I was looking forward to seeing old friends here, I've only seen one so far in church but she don't go every WK, she just went the one time in months just to see me. I got an apt here so I'm not homeless or anything. its just that I feel like I got ripped off. I thought it would be fun to be with old friends and go to church with them but I've only seen one in the month. I've thought of going out more on my own but I haven't been feeling the greatest myself, I have swollen legs and feet and I found out they were from blood clots, the doctor I saw here I showed him my legs and I got sent to the ER. I also have a small one in my lungs. I'm taking blood thinners for a month and hoping it goes away. haven't even told my friends about it, not going to if they don't seem to care about me. I'm starting to regret moving here. I enjoyed it here a lot yrs ago, wondered if I should just go somewhere else. I'm not broke so I have the money to do it, any suggestions?
