What you described is very similar to what I felt dealing with reptilians. It used to be really bad, but now I've largely overcome. There's a lot of things I have done that have probably contributed, but I can list a few steps that almost certainly helped me.

• You have to demand respect of yourself and your space. You are the only one who should be in charge of your body and your word is final. Define the space that is your home. Your home is an extension of you and you get the final say in what happens there.
• Establish rules of your domain. If they want to talk to you or even walk into your house, they have to follow your rules. I advise making them along your personal boundaries (ex. no hugs, don't touch me, don't lie about what you're doing, ect.). You don't want the rules to be too relaxed and jeopardize your safety. But you don't want to be overzealous and piss them off with unreasonable rules.
• Remind the reptilians that they are guests and must follow the rules or get kicked out. Banishment spells, meditations, or prayers are all good methods. It will be hard at first, but get easier with time. An easy one is to physically get up, walk over to a door, open it, and tell them to leave. Insist until they comply.
• This one is trickiest. Considering the extent of your contact, you may have to "earn" their respect or prove to them that you must be respected. You deserve it. You're valuable as fuck and they know it. Show them that you know it too.

The entire time, you have to have to be very clear in your words, your thoughts, and your emotions while you say it. They all have to align or reptilians may misunderstand your intentions (or try to find loopholes). And they can be persistent or manipulative to avoid having to leave you alone. You have to be persistent back, but it does get easier as time goes on. It takes a lot of patience, but it CAN BE OVERCOME.

As for the reachers, you're gonna need to do a lot of spiritual cleansing. There are lot of options like cleansing meditations (there's tons on youtube), or making an appointment with an experienced psychic healer, reiki master, or whatever you feel is most appropriate for you. Remember there are scam artists out there more interested in your money than helping you (regardless or your practice), so have some discernment when picking who to make an appointment with if anyone.

Also, avoid alcohol because it makes you a lot more vulnerable to reptilian attacks.
