Feeling Scared When about To Sleep

I have started to feel like im scared to go to sleep, i get very relaxed and then i start to get palpitations and panic, although i try to calm myself down i dont stop thinking about it until i fall to sleep.

The feeling of sleeping maybe scares me.. Im not sure if this is anxiety ...? I have lost my apetite too and am not really feeling the happiest lately, but even before i was having trouble sleeping. I just kind of worry about everything, not continuos

Thansk in advance if someone can help.
