Hobbies. As you know I have several. They fill up the Space/Time and I learn. I read. I Paint. I create. I go out and do something. A Hobby does not need to be anything big or complicated. It can be as small as a stamp collection, or as busy as working on vehicles.
You're never really alone. I used to think that all the time until I met other parents that are like me. This community helps with that. (Thanks guys) Also there are plenty of groups and resources you can use as far as making friends and support.
When we moved, we found a church with a strong special needs program. In addition to having classrooms for different age groups, they also had a small group for parents of special needs children. After a two months in there, we found it a bit of frustrating - since everyone was struggling with their own issues, we never got really deep. We eventually moved to a different small group and found that some of the people in that group volunteered with the special needs classes and already knew our kiddo. So now we had a group of friends who had a taste for what we were going through. It's been quite refreshing.
My boss at work also has a child with special needs, so we chat every so often. But most of my relationships and friendships are with people who aren't in our "world" so they help draw us out of that world so it doesn't consume us.
I turn to my natural supports my husband, my cousins and my daughter team and a trip to Walmart where someone makes me laugh, ask how I am or get a hug from friends.
I never felt alone. I began networking with parents and forming bonds and relationships in early intervention when my son was age 2. I don't have many friends with "typically developing" children. Joining groups where the children also get to know each other and participate in various activities has been extremely important in my life. We cant change who our children are. We have to embrace them, develop a tough skin, and enjoy you life the best way possible. Some believe in inclusion but it doesn't work for everyone. People can knowingly and unknowingly be insensitive. Find one parent who is connected and they can help you find what you need. Where do you live?
