I know it can be hard to do at first, but focus on one day at a time. Life when newly sober can seem very overwhelming...for me it was like seeing and feeling everything for the first time.
Not to mention you aren't sleeping well so this can add to your stress level. The first month of sobriety I would do days in intervals..get up, get ready for work. Do all the work I can until lunch break. Eat a healthy lunch, tool around on SR, call another alcoholic to chat etc. Then back to work. Get home, go to meeting, eat dinner, bed. Watch movies / read if I couldn't sleep. Hang in there...it gets easier & better as long as you stay sober. We are here for you and you can do this!
