Hello, my best-friend has suicidal tendencys and I didn't hear from her since sunday. 

I do not think/(HOPE) that she killed herself as her Boyfriend was with her the whole extended weekend. As far as I know tho he has to work from Monday-Friday so I guess he is not with her anymore only if he has a day off or she is staying at his place which so far only happend for one day and not more. (They are together for 3 Months, I'm 19, she is in a similar age)

So I'm quite concerned. 

Again, I just cant comprehend the idea that the outcome of this situation is that she is dead. Jesus Christ. 

But nontheless I didn't had any contact to her or saw any activity on social media. Which makes me think that she might be isolating herself. Last week she told me exactly that, that she felt like she is isolating her self more and more. 

I didn't text her a lot over the weekend and there was some (negativ-)tension between us. So she either might be with her bf and doing just fine or she is know in isolation mode. It's been basically just 2 days without contact however it is very very very uncommon for us to have no contact over such a period of time. It's probably my anxiety and she is doing well. I dont want to be to pushy and disrupt her good time with her bf with negativ thoughts. 

Even if suicide is the most unlikely outcome she still could have hurt herself and is all alone at her place and I dont want to leave her like that. 

She expressed to me that she felt like she is isolating herself so how do I act upon that without beeing to pushy even if the isolation has barely started? How do I force myself through negativ responses/bad meet ups. I give my best, but I have to think about myself too, right? I already have my own problems and beeing "rejected" by her would only make it wore but I feel like I have to be there for her. Am I beeing to egoistic?  I really hope my anxiety is right and she is just pissed at me or something.

Thank you.
