Hi Kroko,
Contact these guys by phone if possible.

If you can't phone then email them.
Suicidal thoughts are not the same as wanting to do it. If they were this forum wouldn't have many members. Also, the fact that your sister sadly took her own life does not mean you are the same because your a member of the same family. If this were the case brothers and sisters would have more in common than a clone, and even clones behave differently to the original animal because they have a different personality due to their experiences and character. What you have in common with your sister is you have the same parents, there the similarity begins to fade.
I may have dropped out of sociology due to ill health Kroko, but when I did I was top of the class. I also have a 1st from the University of Life 1961. So please believe this college drop-out when he tells you not to worry and that you will begin to feel better once your medication kicks in. If you have been taking this tablet for more than 6 weeks I strongly suggest you go and see your GP and tell him what you have told us, he will very likely change them to another sort.
Regards,
Blue
