where the hell do you live?
as for shooting the .380 - go to a shooting range. Just go do stuff that you enjoy doing. Hell when I broke up with that girl, we went out and played some video games ( just something I love doing lol ), next day we hit up Road Atlanta.
Don't use your Aunt as a scapegoat, otherwise the next girl you're with the same thing will happen. I'm not sure what school you go to, but if they have any on campus housing, maybe thats a good option. I myself am about to move out of the house ( just me and my mom ) and go to Marietta to SPSU. Granted I will be back weekly just to spend time with my mom cause I'd hate to leave her alone ( her and my sis aren't on speaking terms really )
In other words, use this time to I guess reflect on things and what you want in a woman ( don't say her, she was perfect etc, you can find the same qualities in another girl if you look around - I did, it scares me

) - and I can't stress enough to focus on school, and work ( if you work )
