You seem to be still anxious about this. Just go back and read the answers given to you on your other - similar - thread.
If you really have blasphemed the Holy Spirit then you will have to suffer the consequences but I really don't believe you have. Believing a lie isn't blasphemy. The enemy is always telling us lies but as we mature we learn to recognise them and refute them.
You need to ask God to show you His love for you as it seems you have a low self esteem. God is a god of love, a Father who knows that we are just dust.
Psalm 103:13-14
As a father has compassion on his children, so the Lord has compassion on those who fear him; for he knows how we are formed, he remembers that we are dust.
Instead of trusting in your own judgement of yourself trust instead the Word of God. We are to judge nobody, not even ourselves, so turn to God and don't beat yourself up about something that happened when you were 14. How many years ago was that? Years that could have been filled with love and joy and peace.
It is so sad that Christians do beat themselves up instead of living in the joy and abundant life bought for us by Jesus with His own blood.
It sounds to me as if the Christians you encountered as a young lad must have been of the hell fire brigade rather than have the compassionate nature of Jesus.
Forums like don't always give you a true perspective on things as there too many points of view but I went back and read some of the answers on your earlier thread and many of them make sense.
If you can it might be better to seek out somebody face to face - someone you trust who will not condemn you.
John 3:17
For God did not send his Son into the world to condemn the world, but to save the world through him.
Hope it helps, but really it's up to you - you have to let go of your fear and anxiety.
Philippians 4:6
Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God.
To close, I would say that there is more to the bible than the bit about blaspheming the Spirit. Start reading the gospels prayerfully and with an open mind.
