You are still so incredibly young
I say this as someone almost twice your age and been where you are with ex boyfriends and ex friends - but these people who cut you off on the say of someone else are not your friends. True friends don't disconnect from people just for the sake of it.
I know you have been feeling this way for a while, and it's so hypocritical of me to tell you to hang tight for a little longer but most of my attempts were impulsive and failed. I first tried to CTB at 14, and I have had countless attempts since and have hit the grand old age of 37. I have a rough date for CTB (start of August) and I will be following through this time in spite of all my past attempts. But I'm glad I am making this decision as an adult who has lived and had experience. It's planned, well thought out and I am at peace with it.
As much as I have lived in a hellhole mindset, there has been a lot of goodness intertwined that I would have missed had I been successful. And I cherish those moments and wish they had been enough for me to break this cycle I go through.
I think my rambling is trying to say that you potentially still have a full and beautiful life ahead of you. And as a tender young age, it's so hard to believe and see that. But I'm always hoping that somehow people can see that things can get better. And if you genuinely don't feel that way, we support you in whatever you decide. But don't give him satisfaction of doing anything on his say….
