Spending addiction??

Hey everyone. This is super embarrassing to admit but I genuinely think I have an addiction to spending..or something's wrong with me. My friend is 15 weeks pregnant and I'm so excited for her. I wanted to spoil her with everything I class as nessicities and soem nice to haves for a baby. I'm not rich. I don't work. I'm a stay at home mum. Well guess how much I spent on her? Just over $300 aud. And now I'm sitting here feeling bad but also like I can justify it? Please don't judge me. I won't admit this to anyone because it's actually really embarrassing. Every now and then I will do a big shop for stuff I want for either me my kids or soenthing I'm passionate about and I spend with my heart instead of my head. These spends end up being a whole pay check ( centrelink money) while my partner works hard to pay for bills food and everything. I've had days like this where I'll spend all the money and feel bad about it. Or sometimes I feel great but then I'm liek oh actually could have used that to feed my kids which don't get me wrong they don't go without. I really just.need some guidance. She's not a super xlose friend but I was blessed by everyone during my pregnancies and I want to be able to do that for her. I really just need soem guidance. I don't know what to do but I think.i want to change. This can't be healthy. I don't know who to talk to because it's not alcohol or drugs and I'm worried I won't be taken seriously. Please help🥺💖
