You need to ask yourself some pretty serious questions about your motivation for joining the Army.
Joining any military service is long term commitment and not really something you should do simply because you think it may be the soft option when it come to make decisions about your future.
Go down to your local ACO and have a chat with the recruitment officer, they will be able to help you make the right choices.
I was in the military for 18 years and I never ever regretted it, but it is a serious commitment and is not for everyone, so be sure that it is what you want to do, and not what you think you need to do.
Ignore the naysayers, being a soldier can be an extremely rewarding and lucrative career, just be aware that it is a way of life and not simply a job that you can leave at anytime.
