I Injected Meth For The First Time Ever This Weekend.It

I injected meth for the first time ever this weekend.It was the dumbest decision I've made in my 26 years.I have a few symptoms.The right side of my bottom lip is swollen.Also a little under my jaw
There are a few sores inside my mouth.Sometimes I still get really light headed and natiaus.My heart rate is fast at times and I am either really hot or cold.I can't believe people turn to this stuff to feel good.I have never been so scared or felt so bad.Addiction is a no way for me.Just want to get it out of my system and repair the damage I've done.Please help
