Is it better to self-harm for immediate relief or hold out for long term improvement the hard slow miserable way?

I can say with personal experience that even though the long route seems tiring and hard compared to the instant relief that hurting yourself gives. I used to self harm because I felt guilty and 'not good enough'. I guess cutting myself felt like I was punishing myself for all my short comings. I also did it for attention seeking help. But no one recognised that. I had supportive friends who got me through that by reminding me of my self worth. I do not know why you harm yourself but I sympathise with you and I just want to tell you that you are unique and loved and you do not need to harm yourself for anything. I hope you get through this and hope you have a good day :)
