why am I genuinely so unproductive

like, I'm on Zoloft. it should be making it easier for me to retain serotonin and, yk, be motivated enough to do shit but it lowk only increased that probability by like, 10 or so percent. idk if its gonna get any better since I've only been on 50mgs for like 3 weeks and I don't trust 100mgs cuz that crippled my ass for a solid 2 days fml. anyway, I had my resume open and yk ready to work on again only for my dumbass to forget about it and watch yt for most the afternoon/evening. I rlly need to stop doing that but its challenging as hell and my commitment to try and stop can never last more than a solid 5 hours if I'm being completely honest. any tips to try and fix this issue are appreciated I struggle HARD with this dawg 😭😭😭😭😭😭😭
