i need help

can somebody please give me some support to stop picking my face. i am an 18 year old girl and i have been doing it for years. i am ruining my skin i already have horrible scars and huge pores. i dont even want to imagine what my skin will be like when i am older. i need to stop now. i have tried so many times and i keep failing i have had therapy and seeked help from so many people even my family and nothing helps. sometimes i want to admit myself to a mental hospital because i feel like one day i am going to completely destroy myself. i get so upset when i pick. the whole time i am thinking "why am i doing this?" but it still isnt enough to get me to stop. i dont even have bad acne, i make my skin bad from squeezing and causing scabs and infections. i want to try again to do a challenge to stop picking and i want people to help me and do it with me. 30 days is far too long. the longest i have ever gone is a few days. for me one week will be a massive achievement. i need to stop i am ruining my life i am not achieving any of the things that i want to achieve and i am not the person i want to be. my general health is going downhill because of how depressed i get for days after squeezing. i really need support from people who understand. i am sick of pouring my heart out to people and asking for help only to realise that they have no idea how serious it is and think it is normal to squeeze at pimples. its not normal to spend 3 hours in the bathroom almost every night. i have waisted so much time and my relationships with my family, friends and boyfriend are going downhill fast. i have had enough i cant keep living like this i am desperate to stop i feel so weak and pathetic i wish i was someone else sometimes. somebody please help me to stop this i am ruining my life.
