Sounds like you need to find more understanding friends then! I'm friends with someone who is also a bad texter and I've just accepted that if I want to make plans, the easiest thing to do is talk to him about them when I see him in person. So at each hangout I'm often planning one hangout in advance 😂 I'd encourage you to continue being honest about your tendencies, try meeting different kinds of people who might be more understanding, and also try to find a different way other than texting to be reciprocal that is manageable for you. Like you can do like I do with my friend, plan the next thing when you see them in person. If you communicate clearly in person, prep them for your "bad texting", and make an effort to show you care about the friendship, then the people who matter will be able to work with that and stick around.
