so much to say, how do i say it?

I have so much to say but always get hung up on how to say it...
Hey people of the blog. I have always struggled with speaking what is on my mind, and not because I lack vocabulary, but rather because I am not sure how people will respond or if I will relay exactly what I mean. Then there are times where I blurt out what pops in my head right away without thinking and sometimes it is funny but a lot of times it comes out kinda rude or mean lol.
Like I said before I'm not very good at blogging, so if there's something you want to read from me subscribe and leave me a comment ;)
Make it a great day!
