I really don’t know how to type this so I’m sorry if it’s messy and poorly worded

I haven’t felt like myself since before Christmas and it doesn’t really get better. I’ve had unhealthy coping mechanisms which I don’t want to list in case I trigger someone. I really want to get better and get some sort of help and I want to open up to my mum, I’m really not sure how to. I should’ve done this a long time ago but I didn’t and I’m not sure why but I know it’s time but I don’t know how to ask for help, like what to say or how to say it. It sounds ironic but I’m asking for help on how to ask for help.
