plane guy. Your feelings are normal but you have to start thinking long term. You are clearly motivated, otherwise you wouldnt even be asking this question. I have been involved with this sport for 21 years and know this very well, worry and doubt is a waste of your mental energy. Let go of it. You run a day, if you miss a day or two due to your schedule, then simply get back out the door when you can. If you have to get up at 4am to get a workout in because you have a meeting or something to do at 7, so be it. Dr. Joe Vigil, said it best, "there are 24 hours in a day, if you have a number of things that you have to do, compartmentalize them so you can do them all.

Is your goal mainly to run or soccer drills, lifting weights? Find out what has the most priority on your list and nail it. Hone in on where it is you have the most passion for in those three areas and lessen the lode on yourself. You will be more focused and less stressed..but you have to let go of the thoughts and concerns. Control what you can control. Hope this helps.

I wouldn't worry about missing occasional days.  Hopefully you are not doing the same weight routine every day.  You're better off alternating between, say, upper body, lower body, core, so you have recovery time between workouts for each muscle group.  You might also try doing a longer run a couple times a week - don't know what distance you cover in 30 minutes.  Longer runs will help your endurance late in the game.
