Where you have life you have hope, with your boyfriend you can gain strength and direction and hopefully find the power to get through this, remember you only have to be you so just try to relax and be yourself. Talk to your boyfriend about these feelings he might be a world of strength and or contact a local helpline. Just because you now feel different inside this might pass or become your new normal and in time you may accept this and not fear it, please choose life. My son took his life this year, he had no real problems he just gave up, whilst I try to understand and hope he in a better place I wished he had reached out. I wish you the very best in life.
Be you for you and remember no one is perfect.
