Making plans with people

I don't know if it is just me the is having some bad luck, but the last 2 months or so, every time I had plans with someone or something like that, they forget. The simply just forget. Or they get double booked, or had to be with the family.

What did i do? I barely have time for my friends because of school and cheerleading, but when I do have time and make plans with people they forget about it. I've stopped reminding people that we have plans. I wait for them to realize  it. Also to see if they really wanna see me, or if they are just playing nice with me. 

I hate it.
