I don't write a lot, so I will make it short.
I am unhappy because LIFE SUCKS.
Will it always suck?
Your question is too short to figure out what the issues are, so I'll have to guess. Dead broke, no job, fights all the time at home, car trouble (or no car), living with your parents, her parents or with friends? If you are totally dependent on others for your survival, life usually does suck. Many people I know blame everyone else for their woes, thus lessening the burden of personal responsibility for their own lives. I try not to base all my counseling advise on the million songs rattling around in my head, but sometimes I can't help it. I refer you to George Thoroughgood (of "Bad To The Bone" fame):
♫ Get a haircut and get a real job
Clean your act up and don't be a slob
Get it together like your big brother Bob
Get a haircut and get a real job ♪
In other words, make a reasonable plan to improve your life and begin. A positive, and hopefully not overwhelming plan may involve: finding a job, getting affordable housing, get transportation, including a bicycle, don't smoke or drink up your moola, be a loyal and loving mate and work consistently at improving yourself would help to de-suckify your existence. Or do nothing and you'll always have lots to complain about.
