I need advice

Ok so I have this friend and the last time we hung out was November 3rd and then we tried to hangout the next weekend but I got sick and then we tried Friday but she had a covid scare so we have just been doing zooms and we did one on Friday and then we haven’t done one since and I feel like her and I aren’t friends anymore because we don’t hang out as much as we do but she has volleyball from Monday-Saturday so I understand she is busy but on Sunday we could because she has a free day but every time I try to ask to hangout she’s like I can’t sorry I’m busy or if I try to do a zoom she’s like sorry I’m busy and she’s one of my best friends and i don’t have many friends and I just feel very lonely so I always try to do something with her but it never works out. And idk if I should talk to her or what. Any advice would be nice.
