Is this evidence i have the Holy Spirit?

I try to do whats right and obey God, when i do sin i appologise, i tell myself "benny, dont worry your saved and God loves you" i feel im going to heaven, im looking forward to it, im not always ured but im convinced in the end it will work out, i believe Jesus died for my sins. Also i pray to God and i believe you cant pray but only through the spirit. I try to comfort others and spread the word of Christ.
