The others are right, it is probably not going to change.
From that short sentence it seems that your supervisor is doing a lot of things at once and you are low in the priority list. I don't think it's personal (unless you have clear evidence for the contrary).
If you're not ok with that (some people prefer being able to work in peace) and you cannot change it (some profs are like cats, show them something interesting and you'll have more of their attention than you ever wanted) see if there is someone else around to help. Are there any postdocs or other seniors who could fill that hole? Also talk to the other PhD students and see what their impression of the supervisor is.
It is very important that the supervisor/group and you are at least a decent fit. Think about what kind of working conditions and supervision you need, (and what would be harmful), and then consider if the match is good enough. (For example, do you want to be left alone or do you need closer mentoring? What kind of mentoring? Do you want to work with peers?) If in doubt about something major, you could also try to talk to the supervisor directly.
The most important thing for your mental health is mostly not the research question but your research conditions. Please take care of yourself.
