I really don't feel Happy?

listen...ive got enough problems of my own and i wasnt put on this earth to cry everyday

You're not in a good place are you? Firstly, your dog loves you unconditionally. I own dogs but only need to take them out twice a day if that; they are more than happy to run round the garden and then sleep. Perhaps she doesn't need that many walks but by doing it, you are escaping your problems. The children at school who are bullying you; tell a teacher you trust; so they can support you and try and solve the problem. Bullying is NOT acceptable wherever you live and it needs to be dealt with.
Have you tried doing small jobs to help your parents with the business, or even making dinner. Just little gestures to help them, even running a bath for mum might help. Your parents recognise you are lonely by buying you a dog; a dog needs attention and, I guess it stops you being underneath their feet, so I can't understand why they are saying they'll get rid of her. You need to think of positive things. What would you like to do when you finish high school? Don't feel left out with the two girls who are your friends either; share with them or even arrange to see each of them on their own so you can build a relationship with both of them. Is there another person you could introduce to your group of 3 to even it up?
You life will get better, even if it's rubbish now. Your dog would not be better without you and nor would your parents or siblings. Have you spoken to them about how you feel? If they're older then they may be able to relate to how you feel and help you. If younger, then perhaps your parents know they need to spend more time with them and don't realise how you feel. Perhaps write a letter or a poem to them so they know how you feel? Speak to a teacher or a counsellor at school for advice. It's always better to talk about problems as then you realise that others feel the same way as you. A problem shared is a problem halved.

Listen kid, I am ugly too and my life had suck for a while but I am trying to work things out
Try joining a new club and make some new friends, the real one.
Try to be charitable, like helping people, hopefully they will love u back
make new friends, talk with them, chat with them, help them if they need any.
after helping out other people, those people might give u the things that u always want to have
say because u help them out, they may decide to give u a gift as a token of goodwill.
so don't get discouraged. There are lots of good people in this world that are willing to help each other. You say you are struggling to pay bills/in debt. Work hard at your studies, get top grades, enter uni, get a wonderful job, earn big money, and then it will fix the problem.
Life is rough, I know, your life may not be perfect but you can make the best out of it. Ask yourself what is your dream? You want to be a good dancer? singer? musical performer? play guitar/violin?
No matter what you do, try your best, put all your efforts into it. Not only will you receive money, but you will also gain respect and make amazing friends along the way. You will be rewarded for your hard work, so don't get discouraged if things turns out bad, it is only temporary, and it will pass.
Just keep working hard at it(your studies/your job) and you are good to go :)
You will be rewarded for your hard work, i.e. good grades, good return, etc.
You don't have to be handsome to have someone to like you; it is what you do that matters.
It is your action that counts/ticks the clock(time). Look the clock is ticking so make good use of the time to do good things, like contributing to the society, dedicate yourself to help others, e.g. do voluntary work and giving money to the poor,i.e. the beggars/lonely walkers on the street begging u for your help Help these people and you will see yourself properly returned spirtually
you can also donate money to charity organizations or do some charity work
Good luck sis and may the force be with you :)

who feels happy anymore?
