Hi I'm new to website

I had a question about the unforgivable sin. I have been confused my whole life about religion and to make a long story short my mom was Mormon my dad was catholic but never whent I found out that he wasn't my real dad at 12 and parents argued a lot I was a good kid my heart was good. I became timid and had low self esteem at age 16 I got addicted to drugs and tha whent on for twenty years I hated myself I was the totall opposite as when I was young and made a lot of bad choices. I'm 37 and I'm seeking Christ and I'm overcoming my fears and my hunger for Christ is my passion I can't wait for church. I don't no if I said anything bad to the holy spirit and might of denied god existing during these horrible years. I attend a born again Christian church and I have been sober now for a couple of months and when I read about this sin I've been worried
