u/Strictly_unneeded

I’m 14 (mtf) right now. Been looking to get on puberty blockers with my mother recently. We got a referral from a psychologist. The gp gave us a list of places to check out, and we got a consultation for a children’s place in September. I’ve heard waiting lists can be long however. I’m considering DIY. I floated the idea to her in case plan A fails/takes far too long. However she said she’d prefer to stick with a prescription. Does anyone know how long it might be, and have any good way to convince her that DIY is safe?

I play mainly Riven, Aatrox and Darius. I have beaten a Garen once or twice only as Darius by taking stormraiders and cheesing. I haven’t beaten him in lane on any other champ so far as I remember. I’ve been playing league for 1.5 years. I can’t contest his sustain. So naturally, to beat sustain you look for an all in. But if I try to all in he can either Q and sprint away using W to beat any potential cc or e to stack conq and threaten a kill. Even if I try to theory with a lvl 3 crash using lvl up timers to get prio, his e means if worst comes to worst he can just free farm.
How do I beat him on other champs or just survive his lane more consistently?
