Scared of everyone

Hello everyone i feel scared of everyone in my life I have social anxiety which I'm trying to control but I want to hid anytime I see somebody that I knew from my past I don't get anxious by my family or other people but yesterday I got a message from someone I knew and he wanted to come up later this year but he didn't say he was coming definitely but then I feel depressed and scared of actually seeing him or other people that I knew. I have a stutter which aswell I'm trying to control better now but even when I see people I stutter and get more nervous I don't know what to do i just want to be brave and have confidence but everytime I here or see something that I saw in my past I just blush and get hot and then I feel more depressed because I know I'm not ready. I came out of school 4 years ago now because realising now that I've had social anxiety for my whole life and came out of school because I literally could not cope and it was getting worse I'm better now now than I was but I just keep getting things in my way like with the person that wanted to see me I was thinking should I text him and give him my phone number or not and see him and this was not from him it i created a Facebook account and texted him but then I thought I don't like it and got nervous I thought he did not get the message but yesterday my sister who is friends with his mum said he got the message and might come up later in the summer and I just got very anxious and completely shut down and got depressed and its not like he will definitely come because hes busy but I just got very bothered about it. And I do find it hard to go outside and in to town I'm getting better with everything and going out more but I just find it hard to talk to people with my stutter that makes it worse with my anxiety. But I find it hard when things pop up from my past that I knew I just get bothered.

Hope everyone has a nice day

Toby :)
