When you are feeling down, vulnerable and your emotions a mess, many people will reach out to you. In my experience most mean what they say and are genuine in their desire to see you feel/get better (personaly experience from here xx).
Then you get those that prey on the vulnerable. They see an opportunity to perhaps get you entangled emotionally and being in that delicate state you may allow it to happen....with out necessarily realising what is going on.
Always tread carefully when you are in this state of mind. You don't want to get even more disillusioned than you already are. It can be so easy when you hear someone caressing your feelings with well oiled words.
Just putting that out there.
