Im 26 and felt the same way last year. I saw my friends graduating and having kids getting married and going out the country traveling and looking all professional and shit with their degrees while i was out getting fucked up partying and getting arrested. Im 17 months alcohol free and 22 months coke free and this is the best ive felt my whole life. Last year i thought i was wasting time but im glad i went thru the whirlwind i did. I accepted a lot of things and learned a bunch and now im ready to be the best version of myself. No where to go but up buddy. The past doesnt exist and neither does the future, only the current moment does, all u can worry about is what youre doing rn and building yourself up step by step. dont let the past hold u back, u cant change it. You write ur own future
