Between a rock and a hard place

I'm in a hard spot in my life right now. I have a lot of built up anger and feelings inside of me and I have a bad habit of not letting things out. I've gotten better but sometimes things are just hard for me to talk about. I've gained a lot of weight due to stress and a hormone imbalance and I just feel disgusting all the time. I want to loose the weight but I work my ass of for my job so by the time I get home I'm exhausted and just want to lay on the couch and watch Netflix. I also have planters fashitis (bad spelling 😬) so on top of everything else, my feet KILL ME at the end of the day so the last thing I want to do is any type of movement. I want to take up kickboxing cause I feel that I would really benefit from that but I don't have any money to pay for classes nor do I have the money to buy myself my own punching bag or even a gym membership. Does anyone have any suggestions as to what I could do? I know for sure I need to eat WAYYYYYYY healthier but it's just really hard cause I'm on a super strict budget cause I literally have no money and it's hard to buy good food cheap. I just have zero motivation to do anything. I'm in a higher dose of my birth control cause my emotions and hormones are like a freakin roller coaster. I'm so evil sometimes and then .5 seconds later I'm crying and then the next I'm laughing. So I'm hoping when I start this stronger dose it'll help with that...? I need all the tips and advice I can get ladies!!! Help me please!!!
