Why am I feeling so negative about us?

Me and my boyfriend have been together for a year and 7 days now and I love him dearly…we used to see each other a lot like 3 times of every week of every month. We are very affectionate and we show it …but now lately he’s been working weekdays 12-5 and Saturdays 11:30-6 and I work to so finding time for each other is hard…I lately have been feeling weird. It can be due to the time of month which is coming soon and I am kinda getting sick too. I been also working a lot more then usual myself. I usually only work 2 days during the weekday 4-9 and then weekends at whatever shift…but these past 2 weeks I’ve been working like 3 days a weekday and working like 9 -10 hrs shifts on weekends for 2 weeks straight. I’m trying to get in to college and haven’t recieved my test results for one of them when I should have like 2 weeks ago and I lately feel like I’m drifting away for my boyfriend for some reason. I’m thinking that I don’t have the same feelings for him, yet I can’t go a day with out talking to him….he notices it too. Why am I feeling and thinking this way?….I really don’t want to be like this it’s driving me crazy…I do love him cause if I didn’t I wouldn’t be crying as of right now while I’m writing this….I really really love him and I really do see myself with him in the near future …
