First of all what evidence is there that Scott struggled psychologically because of her adoption? Even Sheila didn't struggle psychologically because of her adoption, her failed marriage and post natal depression took care of that.
As for their financial situation how can you compare a business that lost hundreds off millions of pounds to a rumor of a minor drug debt?
It looks like a variety of things came to a head.
1) She was going to turn 50 and feared Jagger would break up with him because he said he would only be with women under 50
2) She desperately wanted a family of her own but Jagger didn't want to have any kids with her. She was now too old to have children and regretted her decision.
3) Instead of improving her company ended up losing hudreds of millions of pounds.
She was depressed because of all these things. She didn't have kids to help take her mind off he rproblem the lack of a family of her own was part of her problem. Her business was her life and it was in the toilet. Many people in her place would struggle on but some like her would give up and commit suicide.
Note that she didn't kill Jagger and then commit suicide. Her depression resulted in her taking her own life.
Sheila was murdered along with her parents by her brother. He wasn't a murderer because he suffered from adoption problems. He murdered because he was lazy and greedy.
Adults who were adopted as children don't always have mental issues. Those that do have mental issues about abandonment or not being wanted rarely end up killing themselves or others as a result. Most suicides or murders are driven by things that are universal- greed, heartbreak, financial ruin, a loss of some other kind etc.
Suicide crosses the mind of a large number of people. Those who act on it ususally don't have a strong support system.
Murder-suicide is a different animal.
This case didn't involve suicide of any kind though just murder for the oldest reason in the world- greed.
Oh Skipio you respond with such fervent ardour

The evidence L'Wren Scott struggled psychologically with being adopted is based on the link I posted above which quotes her ex-lover. I rather think an ex-lover is going to have a better understanding of her mind set than tabloid speculation over her floundering business/associated debts and not having a family of her own.
Her business debts according to the press amounted to circa £3.6 million (not the hundred of millions you quote) against her partner's net worth of £200 million. SC may have had a small drug debt but its all relative eg against her family's net worth circa £436k.
Perhaps she was unable to have children biologically. If it was that important then I am sure she would have delivered with or without Jagger's input

In his dreams he may not have wanted to be with a woman over 50 but in reality he is now 70 and without wishing to sound ageist or rude well past his sell by date. He was lucky to have a partner two decades his junior. He was hot to trot when he was younger but I wouldn't want to wake up beside him now that's for sure. He is very wrinkly.
If you want to use smokescreens with SC's mental health eg failed marriage and post-natal depression be my guest but I think you will find most modern day mental health professionals would see these as consequences of the underlying issues rather than causes.
I agree adult adoptees don't always have mental issues. In fact most don't, but the FACT is most don't have an adoptive mother who becomes mentally ill so much she requires in-patient psychiatric care as a result of her decision to adopt her first child. Regardless of this FACT all the studies show that adoptees, throughout their lives, are at greater risk of mental health issues than their non-adopted peers, including suicide/ideation. If you can find some evidence to the contrary please post it.
You clearly believe JB guilty so does it not strike you as a little odd that his adoptive mother and adopted sister both suffered with serious mental illnesses and JB is serving a life sentence for murdering his entire immediate adoptive family. There can be no genetic propensity towards mental illness, personality disorders etc. We know JB and SC come from good genetic backgrounds.
Sheila's Birth Familyhttp://jeremybamberforum.co.uk/index.php/topic,2532.0.html?PHPSESSID=01ba1d3b1ea695efd7af04d3b16c4b7bJeremy's Birth Familyhttp://miscarriageofjustice.co/index.php?topic=281.msg4830#msg4830Where is the evidence JB was lazy and greedy? If this was the case why would Michael Deckers and Malcolm Waters, owners of Sloppy Joes, not only employ JB but also have him living with them? I would suggest the reason for this is that JB was an asset to the business. He has carried this work ethic into prison by working out in the gym, studying and working on his case. Its all very well saying well he has nothing else to do but there are I am sure plenty of guys that sit around causing trouble, trying to get hold of drugs, watching tv, playing pool and cards etc.
