Saw my friends at our town purposefully going down the opposite direction when they saw me

It was two of them, we're batchmates and we've known each other since elementary and we were  friends (past tense because it is down to acquaintances now because we don't talk a lot anymore and they have other friends)

As I was walking towards my class, I walked on the left side of the road (based on the picture I attatched, I am also going towards the one lane) which is the most common walkway because it is the path the the dorms and cafeteria it was also lunch time. The right road is meant for cars and it leads to the parking lot, they don't have vehicles. They came form the one lane going towards the left lane but right when they're at the middle, they diverted to the right lane. I know they saw me, I'm a big girl. But I just felt as if they were ignoring me and I feel bad.  

Feeling insecure and unwanted because of this again. I fought with myself for years because I kept thinking that people hate my existance, that they are disgusted with me. I know its absurd but I was extremely delusional but in a negative way, I believed that everybody hated me and are disgusted with me. I had terrible social anxiety. I was extemely afraid of people and I just think that everybody was judging me. 

Maybe they hate me, maybe ive done something to them that they didnt like. They said that if you have social anxiety, you constantly feel as if theres always a social rule that you do not know. And that is correct. Sometimes I do stuff that i do not know is offensive so I just try to not do things or say things when I was at the peak of my social anxiety and it is miserable because you are constantly afriad. 

I do not want to go back to that moment in my life again and I would not let it happen again. I just need to focus on the positives and those are my friends, my friends at my major, my best friend, my friend group, my friends at our department, they are the people that truly matters because I know that they like me and I like them and we are able to communicate, they are my quality friends and they understand me. Now, I just need to not fuck my relationsihp with them. (Idk sometimes I feel like I just subconsiously destroy relationships) If they want to ignore and avoid me then I accept that. I acknowledge how I feel and I choose not to stick to it
