Avoiding or managing a breakdown.

For Aspies, let's face it.  Breakdowns can be avoided.  It's just a matter of how it's detected at it's earliest.
I personally didn't have a good week and the weekend is somewhat of a saving grace.  The only problem I have about this weekend is that I have no plans.  I wish I did, but the few friends that I do have are either too busy, are ignoring me for some reason, or working.  It is the end of April, and it snowed at the beginning of the week, but it did not last.  It was also unreasonably cold for this time of year.  To add to it, my dating troubles continue, or maybe it was my lack of ability to maintain new friendships.  I don't know what happened, but I felt a breakdown coming on.  I could feel the tears starting to form, and I could feel the rage building up.  Somehow I managed to avoid it with a simple text message to a friend, and some pacing around.  The pacing around part did not help, the text message did, as I felt I needed to say something to someone.
Truth is this: Aspies need someone to talk to in order to avoid having breakdowns happen.  The more withdrawn or isolated the Aspie gets, the worse things may get when the breakdown does happen.  I will write a separate entry about an event where this happened.
There are other issues that come with AS, and these are other social or mental conditions.  Such conditions are obsessive compulsive disorder (OCD), bi-polar disorder, and depression which may or may not be seasonal affective disorder.  I am sure there are others disorders, but these are what I have dealt with myself or understand to a degree.  For a person with bi-polar disorder as well as AS, I don't even want to begin to imagine how bad a breakdown will be for them, let alone anyone around during the event.  I have heard a bi-polar episode can be really scary, and I know and AS breakdown can be scary as well.  Combine the two and it must be a living hell.
For depression, isolation has a tendency to lead to being sad.  So does a bad experience with dating or trying to make new friends.  For some, a certain time of year also leads to depression.  This leads to isolation, and depression as well.  When depressed, or isolated, and feeling like I have noone to talk to, or noone wants to hear me, a breakdown is inevitable.  This type of breakdown for me usually involves me yelling and screaming and maybe even throwing or hitting something until my chest hurts.  At that point I realize I may give myself a heart attack if I am not careful.  I stop, and then try and hold back the tears until they just come right down.  This is normal I find for a breakdown, since all of my emotions need to come out.  Just have to find away to avoid getting that angry, I don't like having my chest hurt.
OCD I find is different as the breakdowns are quite minor in nature and I have a tendency to get over whatever is bothering me sooner.  The point here is find a distraction when you realizing you are getting to obsessive.  Go out and do something, talk to friends.  For me as previously stated, I get obsessed with video games, and recently I have gotten obsessed with writing blogs.  While I write though, I have a movie or TV show playing to help distract me as well.  The purpose is to distract me from what I am obsessing over.  I have found the more obsessive I get with something, the more isolated I may become.  This starts the depression cycle again.
If there is anything I don't like about being an Aspie, it is dealing with these frustrations, the isolation, and the depression.  The only solution I can think of to break out of this is to seek help and find a way to learn how to read  and understand social cues and basic body language.

For obsessive thinking- and avoiding a breakdown. The best thing to do is to confront the obsessive thinking.  If someone or something is bothering you and you find yourself obsessing over it, the best thing to do is confront it.  It seemed to work well for me a couple weeks ago.  Obsessive thinking disappeared, breakdown never happened as a result.
For relationships or friendships-  If you have a history of not giving a fair chance due to social anxiety, the best thing to do is to step out of your comfort zone.  The social anxiety can easily cause a breakdown if you are not being fair with anyone else, and especially if you are not fair to yourself.
