Nokia, without knowing your personality, I couldn't really make that decision for you. I have a friend that really can't control his temper when he gets mad, he breaks his furniture, punches holes through walls, etc..etc. Having a gun in his hands during one of his tantrums would probably end in disaster.
You say your having a bad year...any thoughts of suicide? How much easier life would be if you didnt have those worries or problems? I know you wouldn't want to admit to or deny this on a group discussion forum, but again, a good reason to stay away from firearms.
You might want to seek medical help. They have stuff out that will help anxiety, depression or just about anything. Hope you get over your problems, just remember, nothing is as bad as you make it to be...
