Single parenting, working, depression and bipolar2

Hi, I’m not sure where to start. I had a mental health care plan earlier this year but used all my sessions by March. My mental health and mood feels really low right now but I don’t know what to do. I can’t afford more psych sessions.

I’m a single mum to a 4 year old and 7 year old. I’ve been trying to rebuild my life for 2.5 years since being forced to leave an emotionally abusive marriage where infidelity/sex addiction was a constant ongoing issue. People laugh and scoff about it. My marriage ending was treated like scandalous gossip but it ruined my life, it changed everything for my children. People don’t understand how painful it is to go through a betrayal like that.

When I was married I was a stay at home mum, I had a nice life. My ex husband is a well paid lawyer .
It’s been almost 3 years since the marriage ended. Now I work full time at a job I hate and parent solo 70%. I’m struggling financially and stuck in the rental crisis. I’m Unable to get a mortgage despite having sizeable house deposit/savings.
My life feels miserable, like I’m stuck on a hamster wheel. By the time I get home I Only see my kids for 1.5hrs before it’s bed time. Everything is rushed.

There is no quality time with them. A miserable life for them too just having a mother that’s constantly stressed and depressed.

My ex husband still lives in the $2mil family home we shared. He paid me out some money but not enough for me to buy somewhere to live. I know money isn’t everything, I don’t want money, I just want an opportunity to have stable housing for my kids. the kids and I have moved 4 times in 3years.
All I do is work, it’s so much stupid stress and still I’m getting nowhere. I don’t want to jump on the “blame capitalism” bandwagon but I don’t know how I can improve my life or my housing situation when I’m already working a full time job. Feels like society is broken.

I’m so miserably unhappy, I have no time for a real life. I have no time for friends or any hobbies or anything enjoyable. My kids deserve a better mum. I can’t be the mum they deserve, I’m constantly tired.

Once I drop my kids off to school in the morning I cry in my car on the drive to work, I pull it together for the day then I cry on the drive home, I pull it together for the kids for a couple of hours and then I cry myself to sleep. I can’t stop, it’s pathetic.

I called a counselling crisis helpline but they just told me to join this forum. I feel like there’s no solution.

I know I have to stay here because my kids need me. I love them. But it feels cruel having to live through a life that makes me so unhappy.

Sorry I’ve rambled so much. That’s my story. I don’t know what to do from here.
