Almost certainly, although i've never sought help for it. My mother has suffered with depression since I was a child, even attempting to take her life a couple of times, so I know the symptoms. I just kind of power through it so as to not cause any more problems for her... but it can be frustrating at times, and i've even found myself getting angry at her at times for seemingly being unaware of how her actions may have affected me growing up. But I always feel bad later, as I get that it's not her fault. I was only about 9 years old when she first attempted suicide, and there were many more rough times in the years after that. My parents divorced, and I grew up with just my mother and younger sister, so when my mother was struggling there was nobody else in the house to help out. I've never been close with my Dad, he didn't bother to see us much, and I haven't seen him for over 3 years now. My grandparents did their best I guess, although didn't see the worst of it, and they both died a few years ago which resulted in my mother struggling again.
As a result of my upbringing i've always been quite independent. I've paid my own way since I was old enough to get a job, and despite very little support from anybody with my education, i'm now studying at a Russell Group university. That mentality has also stopped me from seeking any help for my mental health. I don't like asking people for help. I just want to do my best and succeed, have a normal life and normal education like my friends, you know? But it is difficult at times, i'll admit that. I spend a lot of time alone, struggle to form real friendships with new people, etc., and that can get to me sometimes. When i'm feeling good, I'm actually quite confident and talkative. I get on with people... but there are many more days when I can barely get myself out of bed, and skip any social occasion that comes up. I can go days without really leaving my flat. I struggle sleeping, often only getting about 4 hours, and I also don't eat some days. But... I get good grades, a 1st in first year and similar grades so far this year. It can be difficult to motivate myself though. I prefer not to go to class and to study alone instead, which I don't think my tutors are very keen on. I keep my attendance respectable though in classes where attendance is recorded.
Whilst I was in first year, it was the day before an assignment hand-in worth 50% of one of my classes, and I was less than half-way through and looking at an all-nighter. That evening my mother had drank a lot and intentionally overdosed on her medication. I had to stop her, and call an ambulance and stuff. She'd already swallowed a lot but I dug a handful of pills out of her mouth. It was about 5am by the time everything was okay and I got home. I had to knock out the rest of my assignment in a few hours before the 11am deadline. I got 54%, which wasn't bad I guess considering, but it was one of my worst assignment grades to date. I probably should have been upset, but I was honestly so angry after the initial shock had subsided. Although, I did go with her to a doctor the following day despite not having slept. I do want to support her. I think the anger stems from the feeling that i've had to get to where I am on my own, whilst battling my own issues, but even now there are still things working against me. Some of my friends parents have supported me more than my own in the past, taking me to university open days, asking about my grades etc. and when I was younger that would sometimes leave me feeling quite bitter towards my parents.
My girlfriend is probably the one reason that I remain motivated, in both work and education. She's the person I feel most comfortable with. She's the only person i've ever spoken to about my family problems, although, i've never discussed my own mental health with her. We met whilst I was living abroad before I came to university, so for 2 years now we've been long distance, spending just summers and Christmases together. But our daily phone calls are one of the better parts of my day. We just got our own place together a couple of months ago, and although I can't live there permanently for now, knowing that i'll visit her in a couple of months and then go back over there permanently after graduation is the one thing keeping me going I think. I try my best to achieve good grades because I like to make her proud. If I didn't have anybody to speak to, there's a strong chance that I may have dropped out by now. I did the same when I was 19 (i'm a 'mature' student now. In my mid-20's). I'm not sure i'll ever seek help now, since i'm over half-way through uni now. I'm always happy when i'm with my girlfriend, so i'm kind of just holding out hope that i'll feel better once we're living together permanently.
Apologies for it getting so long. I was venting a little, haha.
