I suffer from anxiety and just the fact of thinking I injected test into a vein or artery makes me feel ill. How to avoid it? Because there's been ocassions in which a lot of blood comes out after injecting (blood that goes from my glutes to my feet). It's been like 3 times already but after I clean everything is alright and don't bleed anymore. The blood is usually very dark. Perhaps I don't truly inject in a 90 grades angle like I am suppose to? Also, I never aspirate the syringe to check if I hit a vein. Do you guys do the latter? I've been reading more deeply and getting paranoid. Tonight I think I injected a tiny bubble of air. Google says this is okay but still. What do you guys think? EDIT: I ALWAYS inject in the lower part of my cheek.
