What do you mean by "new to Christ"?
Every adult guy I've known who trusted in Christ as their Savior and submitted to him as Lord, immediately got "beat up" in all sorts of ways. Most lost some - if not all - of their friends; others, lost family; all of them began to struggle with sinful stuff in their life they'd never seen as sin before; stresses about all the do's and do not's of Christian living pressed down on them. It got pretty miserable!
Have you ever floated down a river on an inner tube, effortlessly swept along by the current? It's great, on a sunny, summer day! You just lie there on the tube, and enjoy the cool water below and the hot sun above, twirling slowly in the river's current. It's very relaxing. Imagine, though, that there's suddenly a shout of warning from the shore. Some guy is yelling at you that you're headed for a huge waterfall. You've got to stop going with the current or you'll be killed!
When you slide off your inner tube in alarm and drop your feet down to the riverbed - Wow! - suddenly that nice, powerful current that was sweeping you along so comfortably starts pushing on you with all of its force and its really hard to stay on your feet! Getting out of the current is just as difficult, the weight of the rushing water opposing you rather than carrying you along.
Well, this is a lot like what happens when you become a disciple of Jesus and stop going with the currents of your self-centered life. Those currents of selfishness and sin immediately oppose the life Jesus wants to take you into with himself. And they can feel very powerful, if you've been in them for a long time.
You've also got an Enemy, the devil, who usually ignores those he's got "going with the flow." When you step out of his kingdom of darkness and into God's light, though, he doesn't take it well and will begin to give you his unwanted attention. He'll start messing with your feelings and thoughts, causing you to doubt God, and to condemn yourself, and to feel fear and despair. And the devil will work really hard to keep you out of God's word, so that you never understand what it is to walk with God and how properly to do it. He'll also do all he can to isolate you from the Church, the community of believers. If he succeeds in these things, walking with God gets very miserable very quickly.
Just from what you've written, it's clear no one is discipling you. So, check out this website:

And remember: God doesn't save you only if you feel that He has. And He doesn't save you because you've shown Him enough faith, or sincerity, or enthusiasm. No, God only saves sinners because of their trust in Jesus, however small, and their genuine, though not necessarily large, desire to be changed by Him.
Also, God's peace is not first and foremost a feeling but is Himself.
He is the Christian's Peace, not a feeling of inner calm which any Buddhist, or Hindu, or New Age Wiccan might feel. The more you know and enjoy God, the more of Himself will fill your life and flow out of it, including the peace that He is. So don't chase after a feeling; chase after God.
