I had the same fear of having blasphemed the Holy Spirit a year ago, BUT it I am NOT CONDEMNED AND NEITHER ARE YOU. 
The Lord has shown me that I am not condemned, that once you accept His salvation and Jesus Christ as Lord, you CANNOT LOSE YOUR SALVATION!
I used to and still have from time to time invasive and overwhelming thoughts of blasphemy, perversion, homosexuality, suicide, and depression etc. But in order for a thought to be invasive, there has to be someone trying to invade your thoughts with it. It is satan. He is fighting the battle for our minds, but Jesus has already been victorious by dying on the cross to take away sin and rescue man from bondage to satan. We can have that victory by simply becoming saved/accepting Jesus Christ sacrifice for us.
When you have those thoughts, say out loud if possible "I take these thoughts captive unto the obedience of Jesus Christ." listen to good praise music, like not rock or metal preferrably, since these can negatively affect your emotions, thoughts. I know some people think they're dumb/boring sounding, but there are good Hymns. You can read Psalms and the things Jesus said about salvation and that He did NOT come to condemn, but to save. And also get enough sleep cause sleep deprivation causes everything to seem much worse than it is and it's hard to focus/remember, plus it affects your mental strength.
The invasive thoughts are not your own and not your fault, even when you give into them and get mad at God. Satan is stronger than we as humans are, but of course none of you really agree with those thoughts or they wouldn't be invasive. God knows your heart, even better than you do.
When you feel depressed, even after hearing proof that you're not condemned, like I did, I would forget the next day or they would not sound as convincing and i would fall back into depression and feelings condemnation.
Remember, the Lord is never accusing or condemning, He convicts us softly in a way that will gently and lovingly help us change.
Remember to pray to the Lord to feel His love and presence, and even if you don't, He still loves you and He says "I will never leave you or forsake you." Remember that repeated willful sin (such as gross and addictive sins such as masturbation) causes your heart to became cold to the Lord and makes it harder to BUT THE LORD STILL LOVES YOU AND IS WITH YOU ALWAYS.
Remember that the enemy, satan, come to steal (our peace), kill (our joy), and destroy (our lives). But through Jesus Christ we have complete victory over satan, and have those things abundantly.
God bless you all with love, peace, joy, faith, self-control, and patience (God will use this painful, fearful experience to help you love Him and build a stronger relationship with you).
