Oh it is so easy to feel this way! I hear you. To combat the stir-crazies, two big things help me: 1. getting some structure to our week and 2. finding other people in my situation. I got so good at filling up our schedule during the week I actually had to cut back on activities.
- Look for storytimes at your local libraries (ours has programs for as young as one month olds), bookstores have storytimes too.
- Attend meetings for any and all mothers groups you can find. (MOPS, Mothers and More, Meetup, LLL etc) Most groups allow you to attend a couple events before you have to become a member, that way you can check out which ones you like.
- Many times playgroups spin off from these. Check out any local places that have a free first-time visit - Gymboree, Kindermusic, etc.
For me it was a matter of trying to get the most out of this time I have home with DD. I knew there was stuff out there, but the more I looked the more I found. Now we have a specific schedule that happens every week - playgroup on Mondays etc. We're busy and we love it!
As for time for you to get your stuff done, do you have a DP who is available on a regular basis? My DH works a fairly regular schedule so in the past we agreed on certain specific times during the week as my time. That way I'd know ahead that I had, say every Friday evening to myself and that was DH's time with the little one. So I'd look forward to doing me-stuff - craft stuff, whatever, in that time. Right now we have a new little one so I'm not getting ANY me time, but hopefully soon we'll be able to get back into that.
