What would you do in this situation?

First of all, the lives of other people aren't any better than yours... and also, don't be envious of their lives, each and everyone have there own lives...

Well, with your question, what would I do in your situation... well, if I were on your shoes, I would care less about them... I know it is easier said than done, but looks like that is one of the easiest way.. to care less about what they say... don't let them take you down, don't let them distract your life... I will tell you, why should you care less... I told you awhile ago, that there lives aren't any better than yours, because actually, the life you are actually having now is a life you made up... if I were you, I will destroy the thought that my life revolves on how other think of me... and instead, I will create a whole new world for me, a different way of living, in where, I don't mind what people are talking about me, like every person is just a new stranger you have met... well, again, it is easier said than done, but that is up to you... well, I wish I was a great help to you...

You shouldn't be envious of their lives for most peoples lives are exactly like yours. The problems you are experiencing aren't abnormal. A lot of them you do have control over. I'm not exactly sure what was going on with the relationship you speak of for it was very vague, but bad relationships in most cases are very rarely inescapable. As for the four classes you thought you'd pass but failed due to your procrastination, that was 100% your doing. As for what people are saying about you (once more i'm not sure what they are saying for it was a very vague and brief description of the situation) you shouldn't care. People form opinions, and they love sharing those with others. It's just a fact of life and you'll have to learn to deal with it. You need to stop realizing what's not perfect in your life and realize what you do have. You have a family, even if they aren't always perfect. At least you have a family, not everyone is that lucky. You are in college, lots of people can't even afford that. You are healthy and are able to perform normal daily functions. Be glad for what you have and realize that what isn't perfect in your life isn't out of the ordinary and are things you will just have to accept. Also piece of advice, don't use the word "retarded" on public sites like this. I know you didn't mean it in a malicious way at all, but it can still be offensive to some people, especially in a place like this. I wish to you the best of luck!

Your living in the past,your bad relationship was the past.Forget about him,he's gone what he done to you,will be remembered but it's the past.Im not sure what you sister is doing? Or if she has the right to do what she's doing? But please tell another family member about it. When I'm in a depressed/jealous mood i usually just go outside and whoever I see,whoever at all i always tell myself in my mind " that old lady,she has a story,that 12 year old boy he also has a story" . You have no idea what some people go through and you will realise that later in life.At the moment the best thing to do is to really try your best in college because that's the one thing that will be the outcome of your life,your future. Set yourself a goal/challenge everyday,"ok right now I will go to the shop,on my own,and I will come back again" . Just simple easy tasks and try going somewhere doing something outside college ,maybe you have a certain interest? Anyway I hope I gave you some advice that you will acknowledge , Good Luck:)

I would seek what help I can get for the anxiety, maybe through the school too.
The relationship that ruined friendship is gone, so I would think it's time to look for more friends, and would seek public group things to meet new people, assuming I manage the anxiety.
I would procrastinate by googling procrastination but eventually come to fight it with timeboxing techniques like the pomodoro technique.
I would be jumpy around the teacher, but I would remind myself there will always be someone like that in life and avoiding it wouldn't be the answer, but I would also pay attention to what is grumpy and what is abusive so I watch the line and what goes over it.
