First of all, try to begin a weightlifting regimine.
You're already 18 years old, most people start weight lifting for football when they turn 16 years old.
You only practice two hours a week?!
Think of how many hours there are in a week.
24 hours = 1 day
7 days x 24 hours = 168 hours.
Now, assuming you get 9 hours of sleep every night. That takes away 63 hours.
So, you should have 105 hours a week to play. But you're only using two.
You probably go to school. That takes about six hours a day. Five days a week. That gives you 75 hours a week.
For an 18 year old, you should be training at least two hours a day.
Ball control is worked on by juggling, using a wall to kick the ball to you (but give it a lot of effort), and other drills.
Stamina can be helped by running (You know that already). But not just long distance running, but you're not a long distance runner, you're a footballer. So, try fartlek running (if you don't know, search it up). You might also want to try some agility and acceleration drills which you can find on this forum. This forum is loaded with drills and routines.
If you'd like, you can use my Training Routine here:

It will definetely improve your stamina, and should also jumpstart you into weightlifting.
Just incorporate two hours of ball work (I seperate it with one hour of wall work, and one hour of field work [dribbling, shooting]) after each session. That would give you three hours a day of training.
I hope it helps. Good luck![/code]
