Relationship anxiety

Been seeing someone for about 3 months.We’ve only out 4 times due to holidays/sicknesses/work

We haven’t gone out or talked much in a couple weeks due to her work trip. I would like to make plans for the week after she gets back but I get insecure that I’m annoying her even tho I just wanna keep the fire going. I end up over-communicating because I wanna make sure things are clear but yet I feel like I should be cool as a cucumber. Then I start getting worried that I’m turning her off and cling to my phone. I struggle to eat and start using alcohol to numb me. I keep going because I know good things come to those who wait
