Just pray bro, and if going to work on with drugs, I suggest you not to.. Just try to ignore that thing. Plus your family is just the one and only thing you should care of in the life, and which is the best thing you can ever have. And since your daughter is just a little baby, just stay with her and enjoy your life bro; no drugs :/
Also about being a military person, it's simple as going to school. Just ask some people you know so they can help you being a military person. They will support you. And as Zeus said, killing yourself isn't the best idea bro, just try to enjoy your life and being with your family. It's all good bro, just get away of drugs.
