I Wish I Didn't Feel Invisible And Unimportant

I feel invisible so often. And very ignored. People ask why I don't talk much. Maybe it's because every time I try to say something, someone else just cuts in and starts talking about something else entirely. I guess everything I have to say is very unimportant and stupid. Especially with my MIL. I'll start talking about something, and she'll just interrupt me and talk about her side or completely change the topic. Although, it's not just her. Seems that no matter what I say, it's apparently unimportant. So, even though I have tried to be more talkative and outgoing, I think I will just be what I used to be and just never talk to anyone. No one cares what I have to say anyway.
