What you've been experiencing sounds like what I've felt during group worship. I'd want to sing or cry out Jesus, but I'd choke up. Because I had experience with sleep paralysis (which fled when I called on Jesus in my mind) when I first got saved, I recognized this as demonic attack. I kept praying through those moments, and He gave me victory to shout out his name and continue the songs!
While it isn't necessary for salvation, speaking in tongues is a way for your spirit to bless God. Speaking in tongues and interpreting is better, because it's a form of prophecy, which enlightens the church. Spiritual gifts are absolutely essential for the church. The bible tells us to
earnestly covet the best gifts. If you desire a particular gift, ask the Lord and he will bless you in it!
1 Corinthians 14:1-5 Follow after charity, and desire spiritual gifts, but rather that ye may prophesy. For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries. But he that prophesieth speaketh unto men to edification, and exhortation, and comfort. He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church. I would that ye all spake with tongues but rather that ye prophesied: for greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying.
1 Corinthians 12:28 And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues. Are all apostles? are all prophets? are all teachers? are all workers of miracles? Have all the gifts of healing? do all speak with tongues? do all interpret? But covet earnestly the best gifts: and yet shew I unto you a more excellent way.
(p.s. the more excellent way is love!
(1 Corinthians 13)
