I have kept out of this, but...
Starman it is time to stop. Your not just talking, your feeding. You do need to seek help, but not this kind. You appear to be suffer from sever clinical depression and sympathy is not medicine, it is a poison. I speak from professional and personal experience and knowledge. You never have anything good to say. You never have a positive. We need not to enable you and that is what is happening. Enabling means to allow you to continue in this downward spiral. Pity and this type of attention will enable and it is not good.
My eldest suffered from depression and it took us years of patience and therapy to get him past it. It also took my being hard and truthful. I told him to knock it off when he wallowed in self-pity (and self-loathing), but I also sat and spoke with him in the middle of night or any other time he needed it (as long as it got beyond the pity party). I held and talked to him constantly, but I did not allow him to drown in his own self-pity. Stop it. It comes from within, the pity and the hating. I am not saying you can just stop and turn this around. It will take a long time. I remember the days of "no one likes me", "the bullies are picking on me". You can get past it, but you have to want to. You might think that you want to, but do you really want to. Starman, what do you think of yourself? Name a good quality you see in yourself. What do you like about you? Build on it.
Starman, you are in England? Have your parents check to see if the goverment have put laws in place to protect students from harassment in schools. If they have such a law your parents only have to use two words, "Law suit". Bullying does happen and I am also not one to allow it to continue, but violence will not help. I learned that in youth. To help my son I called the school after one of the attacks. The teacher said that my son must have done something to deserve it. I do not just have knowledge of this area, I have a lot of education and knowledge in this area. I wonder if this is your case - People are bullied because they can not defend themselves. Why? Because they do not feel worth it. There is a true lack of self-confidence and self-worth. I told the teacher that, sadly, my son was a complete passive and could not have done anything to deserve it. He was new, he found out I was right. He even asked the bully what my son did. The bully told him "nothing". I called the principal and used the two words. We had a meeting with the teachers the next day and I repeated the two words. My son was never bullied in school again because now teachers did not let it happen. You see, sometimes it is easier to turn a blind eye and death ear.
Taking care of this did not cure my son's depression, that had to come from inside himself. It is only a suggestion if you are really being bullied and not doing anything to get so. It happens. But they will back off if you like yourself and build some self-confidence. You need to get to some professional help. People are going to get sick of hearing it here and that will also not help.
Those that are enabling, you may think you are helping, but has it gotten better? You are only hearing one side of the story. Do not forget that there is another and things may not be exactly as they seem.
Starman, I have a suggestion. Write a post that is not whining and not complaining and see how that goes. Write a post about something you like to do.
Sorry if this offends you, but help yourself.
