Baby scared

My newborn baby, almost one month old, is very scared at night. She feeds and sleep in my arms, thn i try to put her on her bed.. within 5-10 mins she gets up and make her body very stiff, becomes extremely restless and asks for feed again till the time she sleeps while feeding. If i dont give her feed, she cries alot while making her body stiff. I try to out her to sleep again in rocking her in my arms but then also she doesnt sleep till the time she sleeps while feeding. This continues the whole night and she is awake either the whole night or till 4-5-6 am

We did not swaddle her from day 1 so now she doesnt like being swaddled and cries if i try to swaddle her.

Please help me and give me tips as to what can be done.
