Having a hard time with my stutter lately

Having a hard time with my stutter lately I just need to vent with people who understand, and I know you guys will. I've been having a hard time speaking lately and it's causing negative thoughts to pop up in my head. I've always had a positive mindset towards my stutter and tried my best not to let it affect me, but it's hard. I'm falling back to my old way of thinking, believing I was unlovable because of how I speak and doubting myself. It's taking a toll on my self esteem and I'm trying so hard to keep my head above water... How do you guys deal with setbacks?
