The important thing is to realise and truly believe the deep mystery that takes place when you take the Holy Eucharist. Mind you don´t create a link in your mind between receiving communion and a “good feeling”. To be honest I don´t feel any different most of the time (not saying there are no feelings attached to it). It may be even tempting for some to say something like:
I don´t feel anything, therefore it is not real / I received the Eucharist unworthily
However, THIS does NOT follow.
How many times have we been reading the Bible casually without realising what it really is - God´s Word - God Himself speaking to us - mere dust. Or how many times have we realised that God Himself decided to suffer in a human flesh - so much He loved us. And when have we properly appreciated or at least felt God´s existence, presence or love for us.
So do not be discouraged by a lack of “proper feelings”. As for those feelings, altough they may be present, I see them rather as a grace from God to those worthy and/or prepared to accept them (yet it depends more on God than on us to whom He gives and from whom He takes away) than an intrinsic part of receiving communion. And even though we, catholics, may and do generally feel “something”, we should always pay more attention to WHOM we receive that to WHAT we feel.
By the way, if you were just curious then I mostly feel happines, desire to be closer to Jesus or gentle sadness.
I am also happy for your conversion
