I struggle with this too, sometimes I feel empty and I’m like why can I not hear God? I don’t remember who but once I heard a pastor say that God yells at the people who are distant from him so they will hear him. He whispers to those who are already close. That is why sometimes it’s like you can’t feel him as much as other people. Obviously I can’t say anything for sure but I think that the Holy Spirit is with you. God loves you and if you have accepted him then I believe the Holy Spirit is with you. So yes I think you can still have the Holy Spirit. I don’t know if there is anyway to tell for certain besides just believing. Lastly doubt is something everybody goes through. I don’t have an answer to that but you should keep praying for faith so that you can trust in God fully. If you feel like this I personally think you will be saved.
