How do I move on?

Im 29 year old male. I just left a job after 10 years. I was beat down and too paranoid to continue. I now have another job were I am definitely happy and things are alot less stressful. But I still have some issues of thinking about the place I use to work. I started off at that place knowing nothing and had to learn and with learning there comes mistakes. Well these people I worked with hammered me for every mistake. Never gave me a chance either. I got along with most of them and even became really good friends with acouple but eventually finding them joining the others in bashing me about my mistakes. I over herd a real good friend one day saying he doesn't even no how I still work here and that really hurt bad. I even confronted him about it. He just got really angry and denied it. This stuff was getting to be too much. One guy would make a mistake and it would be ok but when I would it was the end of the world and I suck. Every time I see one of these people I used to work with I get paranoid and wonder if they still talk about me or tell people about me allways making mistakes. I allways just wanted to be good at what I did. My ego is definitely dented from all this . I think about this almost every day and want it to go away. At my new job I've been doing my best. Not making as much mistakes as my last job so far and I don't get messed with. In the beginning someone from my other job knew someone I worked with here and told them I wasn't good at what I used to do. So I think I have been proving them wrong because I haven't been hearing about it lately so thank God. I just need some advice to try to get over this. Im allways paranoid and think people still talk about me and tell people how bad I was. It's been about a year now. Any advice will help.
