Hi everyone. I am a regular poster but on on trivial things but need some advice. A good friend of mine has not been in touch for a long time. We live very far away from each other. My calls and texts to her went unanswered for months and months and no response when I sent cards/letters. Anyway I got a call from her out of the blue a couple of weeks ago saying sorry not been in touch and she explained she was suffering with bi polar but was on the mend and now fit and well. No mention of bi polar in the past so I wasnt aware she suffered. I was so happy to hear from her. However over the course of the past few weeks I have started getting "strange" text messages from her. Often about 20 or 30 in very quick succession. Very rambling messages that don't make sense and out of character. I don't know how to respond and not sure if I tell her I am worried or if it is best to just let her keep sending the messages. Any advice?
