Take the time to make your appartment cozy and 'your own place' and it'll work out well.
When I first moved out I wasn't good at planning meals, but I lived two blocks from a grocery store. So, every day when I walked home from university I'd stop by the grocery store to pick out what I wanted to eat for supper. It became a comforting routine and the whole choosing what I wanted to cook and eat even became somewhat fun. If I wanted raspberry pie for dessert I could get raspberry pie - just had to watch I didn't blow my food budget.
Good luck
