Need help on my play, PT and graphs included

I've been playing online for about three months. I play $0.50/$1.00 limit, Sit 'n go's, and multitable tourneys. I'd like some help mainly with my limit play. For my first couple months of play, I could average breaking even or a little above. Recently, I'm doing so badly that I don't make money off deposit bonuses. I just did the 20% up to $500 on PP, which is almost cleared, but I've already lost $100! To me that seems to go way below normal variance, and this is where I could really use some help.

Please take a look at the info I've provided and let me know if there is any more info you need. Note: PF raise is quite low but I recently started raising AJo+ KQo ATs+ KJs+ 99+ so those numbers have been increasing.
