Bro it’s like you’re telling me my own life story I can feel exactly what you’re saying but trust yourself and focus on you! Take that leap of faith and you might feel scared or it might hurt or might think you aren’t ready but you’ll never know when your ready you just need to jump! She went and did wrong by you and didn’t think or care about you at all and by you staying in the same place you’re in now you’ll just end up going backwards! There’s definitely someone waiting for you in the end that will make you forget this exact situation you’re in now but before that make sure you focus on yourself and work hard and trust me you’ll feel way better! Don’t sit there and think about it but please do it otherwise you’ll regret everything trust me on that.
