Friends

Lately I’ve been feeling very sad because I haven’t been hanging out with my friends too much, since they all do the same summer activities and I do not. But it is more than that I think, because there are a couple other girls in our group who also don’t do the same activities, yet they are still being invited to hang out. I haven’t been invited to anything and whenever I ask to hang out, people respond with a simple “sorry I can’t” with no explanation and it just bothers me. I think they may be doing this because lately I’ve been asking all the time to hang out and I’ve never invited anyone over myself just because my house has been in the process of redecoration for the past few months and it’s a bit of a mess. But for the past two days i haven’t been asking about hanging out and still there is no difference. What do I do?
