Fearfull Memories And Stress

I have heard from someone that never to take bad memories from your school or college.It could be true but i'm really frustrated with some of the incidents in the engineering college.

This incident is about my last year in engg.college. i was given a choice to choose a group for project out of 12 peoples.In these 12 there was 8 guys who were comfortable,friendly with my thinking and style of doing project.Here i betrayed my good friend,he asked me to join his side.And i betrayed even some more groups and joined another group,where the guys were underperformers.I thought i can lead them & score some
marks,even if they were underperformers & gangsters.This is the biggest mistake i've done choosing these guys.Instead of doing the project on own they purchased it from some xyz company. As these guys were jealous of my thinking and they totally betrayed me to show the project mentors that i'm the one who is below performer in the project group.They managed to tell my classmates that i'm not performing in project and i'm useless,dealing with project mentor to get them down.At first nobody believed them,but you know when you've bad days even your shadow betrays you.Everyone then started talking the way these guys put forward.This rellay turned me down cause they did all the wrong things,all that i did is i didn't done anything against them.I allowed them to do harm to me just in hope that they will forget me & i don't want any fight after the project is over.

My worries increased for loosing grade in final year.In meantime my good -friend(To whom i betrayed earlier and joined another group) realized this situation and planned somthing to do things reverse,he asked me to talk to mentor and explain the situation.So i convienced
my project mentor about the situation,he assured me that i'll not get much good grades but not bad as well (No loss no profit).Somehow my project members find out about this conversation and they started to threaten me.But I assured them i'm not doing any harm to them in any way.But they continued to do so.In whole academic year i was living in fear,i

used to cry alone and getting angry on my familly members.I was not coming with any social contacts.And then suddenly the project presentation came and everything was over.

Now when i got my marks after exams,i some how managed to get better grades than these guys & i don't know how as i was upset and studied just like i'm doing this for last time in life.And as expected these guys(project members) performed below average.They took these things very seriously and now they are taking revenge on me indirectly using many
other techniques like using social cirlces.Some of their friends who are in contact with me just as classmate are teasing me by saying that "Where is your project group?","Hey do you know anything about xxx guy in your project group?".They are just trying to tease me & want to create fear in me.This really upsets me and irritates me.I want to forget everything and want to live life like new.I don't want to know about them.Everyday i'm
just thinking about what happend last year,this is not forgettable and still turns me down even if some of my other classmate meet me sometime.Their presence enlightens some of the old incidents.Day be day my confiedence is getting down as i'm trying hard to get job in
IT company.This requiers me to concentrate and to be confiedent but i unable to do any good.

I really need something to get over it,How can i get over it? I can't even stop thinking about what happened in the past,i even left the city where i used to live.Now i don't want to live with the old memories.

How can i forget all this,how can i start life over.Is there any chance i get crossed with some of my dark past again.?What can i do to be fearless against them?

How can i deal with some social leeches which are teasing me with thier names?
