Stop overthinking

Any advice is greatly appreciated. I need help. I want to work on our marriage. We have a one year old girl.

I do have a jealousy and trust issues. I’m trying to work on it. My husband has beautiful smart female friends. I’m a SAHM. I get jealous. I don’t feel beautiful nor do I feel smart. I do get jealous that he talks to them. What helps me not get jealous is trying to get to know them. It is me trying to overcome this hideous personality I have. It actually works because they are great people. But then, my other issue with myself is that I overthink. I overthink that what if my husband leaves me for one of these amazing females.

I know it’s me that is the problem, not anyone else.

That’s why whenever this happens, it’s always a step back in our marriage.

Also, I’ve noticed this jealousy comes out whenever I have my period.

Is there anything I can do over come this? Please help. I can’t afford therapy.
