Annoyed and worried with add symptoms and weird boy

I know I already talked about this guy that stalks my family. He also even slept with my sister and has said creepy stuff to my mum. He doesn't seem to get it that I don't like him because he makes me uncomfortable. At this point I feel so worried about him that I bought self defence stuff. I just wonder why I can't get any normal guys but these weirdos that sexually harass me. I got so tired of men that I just haven't bothered coz I just feel jaded at their behaviour. I'm hoping one day a normal man likes me. I don't know if that will ever happen but it seems it's hard for men to respect women and it's like that's the bare minimum why do I have to beg for the bare minimum. Everyone I talk to about jack thinks I should either report him to the police or well kick his butt. I really wish he could leave me alone without me doing any of that. I just don't get why he doesn't understand. He seems to think I'm friends with him but he honestly gets under my skin and not in a good way. I know I've talked about this boy before. Honestly I'm that worried that I don't even like going to the shops because as soon as I do he starts following me. Sometimes people ask me why I don't like him and it's honestly because of the creepy stuff he's said to me and honestly the anger and exhaustion is getting to the point where I just don't know what to do about it. Sometimes I feel like breaking down because it's been going on for so long that now my body is breaking down from the stress. I already got enough stress at home with struggling to get through the day because mum has to fix up after me. My add symptoms annoying my mum and putting strain on our relationship which then makes me feel really awful because I don't want to make her life harder but I do coz I just can't finish a task before I go to others. She's been so irritated that I can only study at school but then at home I have been reminded to do things. Like my independence is a huge problem I've been working with a psychologist and now I'm getting migraines too probably from all the stress and pressure I'm putting on myself to overcome add. I know concentration is not always gonna be 100 percent but I'd at least like a good 70 to 80 percent because the way I am now is just exhausting my mum. I feel bad for her but also the other bits of cleaning well not all of it is my fault because there's also loads of folded clothing that she hasn't done much with and also she sleeps till 2pm and to be honest she can't blame me for that. Even though she does blame me for being depressed and then gets like verbally cruel when I make a mistake but I admit that some of the stuff she complains about is reasonable because we'll I'm not doing a lot. I do my room chores but I really do need to do more washing I don't want to have her hovering screaming at me that I'm not hanging things right. I'm going to continue to try for disability as now I have multiple doctors all saying I have mental illness so maybe the third time will be the time I get ndis funding for my mental health

I hope you can manage to avoid the guy as much as possible
