I totally agree about this summer weather. Some locales are calling it the non-summer or the summer that wasn't.

We only had about 5 days this whole summer where the sun shined and it got up to 70F. (at our summer place in the UP of Mich.) It was frightful...since our cabin is on an island, with NO heat, no running water, no electricity save a little generator.
We had alot of high winds and dangerous waters too.

I wore shorts about 4 times! My flowers rotted. And the indigenous plants were stunted and very late. So we came back early. Normally I stay past Labor Day, but I just couldn't do that this season. We saw an article in USA Today newspaper showing on a map and explaining how the jet stream was moved for some reason, dumping cold wet weather on alot of USA.

I am still catching up, so I haven't read about your step daughter, yet. -- going to now.

edit to add... oh, my, what a summer you had! I am so sorry for your losses. And suicide is even harder to deal with.
This summer about 50 miles from us, there was a huge family reunion.
10 members and a couple of dogs were walking along a road near the area at night and an SUV driven by a guy who had a limited license for previous infractions--lost control or he was intoxicated or whatever, hit them all. At the time we left for home 3 had died, the dogs died, and the others were seriously injured! He fled the scene, and was found the next day. Now he is awaiting arraignment, in a facility far way for HIS safety! It was a totally freak thing. Many were from out of state, and the ones killed were all young women.

Ada, you know we have a Survivors of Suicide forum here that is very welcoming and full of members who can help your step-daughter further if she needs it. Take a look, and see what you think for your situation. That has to be very traumatic for her.
