The truth is, life probably is all of the things you say it is. I will not sit here and write, 'Oh, thats rubbish'. But if you think long hard and deeply about life in that fashion, you sort of channel your mind to actually believe so passionately that life really is rubbish. I tend to channel my mind into believing yes, life has its bad points, trials & tribulations, but this is what makes life quite entertaining. It is there for us to manipulate into anything we desire.
We guide our life, it's only fate and fortune that adds on to it and takes away. So with this, I am at university, I am meeting new people and doing new things and I love life. There are bad things about my life such as my paralysed grandmother and things like that, but nobody can help that. You cannot change what was meant to happen, but you can change what you think and feel.
You say about the heartbreak of love, but what about when you are in love, the feelings which come from it are priceless. What about being able to love your family, and not the feeling you will have when you can no longer love them. I think it's all about tuning in to positive things, not pessmistic, depressing, morbid things.
Life is quite spectacular if you channel your mind to believe it. For me, travelling is awesome, there is so much to see, and simple things like eating new things, and going out with friends. All of this makes life great. If I thought about when my parents will die, if I fall out of love, or things like that, I would shoot myself after 2 days of thinking it.
There's no use going on about less fortunate people either, it doesn't really help the OP, for the fact of the matter is, we are entitled to think these things and should not feel guilty really. We owe life nothing. But if you do think you owe life nothing constantly then you will feel futile. This is why I almost am quite egotistical. Because if I don't think about me, I won't actually do anything. Get out there and get something done, and make your life worthwhile.
The more you think about the bad things, the more they happen. It's like the placebo effect and taking pills and feeling better because your mind thinks that. So if you actually get out there and do something to eradicate those thoughts, then you will actually love life. Sh** happens, and will happen. The strongest people overcome it, and change their lives around. BTW I'm not one of those people who can comment so extraordinarily cold hearted because I have never experienced bad things. Believe me I have had my fair share, but from it, I learnt to adapt to life, and make it what I want it to be. You can be one of those people with a degree who thinks they are owed a job, or a person with a degree who goes out there and shows off their personality and gets a good job. At the moment you are like a person with a degree, thinking life is taking them to places. You control your thoughts, feelings, emotions and where you go, what you like, what you dislike, simply; what you desire - and you have the freedom to do great things.
Bad example really. But shut up now and actually go out there and do something. I take it you are young, believe, when you are 60 then you can look back at your life and think it was futile, just don't think it now otherwise it will be futile.
Also, about suicide, well go on, do it. You probably won't and if you felt so intensively about it, you would have. Its just something in the back of your mind. But believe me, it is a waste at your age to contemplate that. You talk about life being rubbish, it will be for your family when you do it, and then you will have let your thoughts win. Because it will become true, that life is absolutely rubbish. Challenge your thoughts, engage with your mind, and do something stimulating. Cutting yourself to ribbons will not get you anywhere, it will just epitomize the idea of life being so vulnerable. This is what is happening, you are carrying out actions which agree with your thoughts.
