It's a good thing that you keep trying after failure. :)
Tho it's important to know that not every spells work, and I'm sure you read it somewhere, the best spell you can possibly have are the one made by yourself.
You know, problems are sometimes things that you have to resolve by yourself, they are all put on your path to learn.. I would almost say that problems are essential, I'm generally "speaking" here.. I don't know what your problems are but I'm pretty sure you can't just wish them away. A good thing for a start would be to talk :) See I'm here for that, to give advice and I'm pretty much everyone is too.
Now I'm not an expert, I don't want to give bad informations but if I understand well,
the thing about magick is that you gather energy all around and within yourself, through meditation and relaxation, and then you focus that energy to a specific cause or reason. For example, you could try focusing on your problems, you can't wish away your problems but you surely can make things better ! :D
I had problems, I wasn't sure if it would work or not, but I tried anyway. A little confidence spell, as simple as that. Suddenly things started to get better and better.
But you have to believe in what you do, if you don't, chances are it won't work..
What I believe is that believing is a way to focus.. And not just say I believe, I mean truly believing it. Or else it's like you're lying to yourself. Try this and if you need you can mail me, I might not answer right away tho.
But don't give up because nothing works for now, I would suggest starting with books ;)
Reading is a key to knowledge
