@hype_f0rce I would just say keep playing.
I was in a similar place to you but I managed to get my K/D back to positive after constant grinding.
You want to make sure that you learn the map, finding a good squad always helps, practising in the firing range with some weapons that are difficult to control like the R-99 etc.
You also need to think about your rotation and ring positioning.
Don't stress too much about the kills, as you develop as a player the kills and damage will come, this game just takes time and patience.
