Oh I so understand this! I do the same, bombard them with txts until they reply! It only happened yesterday actually and it ruined my whole day as I couldn't stop thinking my friend no longer liked me because she didn't reply. After multiple messages from me, she replied she had been busy all day with house work and the kids and hasn't stopped to check her phone. At this point I felt bad for all the txts I sent and for the fact my whole day had been a day of torment over this.

I wish I knew how to stop this. Just wanted you to know you're not alone
